| Where Was Netflix’s The Final Problem Filmed? All Spanish Filming Locations. |
Netflix’s The Final Problem keeps its murder mystery tightly boxed inside a luxurious hotel, but the production itself travelled across several parts of Spain to create that isolated 1959 setting. The Spanish period drama was filmed in the Community of Madrid, Catalonia and Toledo, with production running from April to June 2025.
While the story makes its hotel feel like a remote island where nobody can escape and everyone has something to hide, the cameras had considerably more freedom. From a major studio complex in Tres Cantos to the dramatic coastline of Lloret de Mar, the production used a mix of purpose-built sets and real Spanish locations to give the series its old-world atmosphere without making every suspicious corridor look like it came from the same building.
Madrid, Community of Madrid, was one of the principal filming bases for The Final Problem, with a substantial amount of production taking place in and around the Spanish capital. The Madrid region provided the production with the practical advantage of having both professional studio facilities and a wide variety of architectural settings. For a mystery built around a group of strangers trapped together, that flexibility was rather useful. The characters may be stuck in one hotel, but the filmmakers certainly weren't.
A key location was Ciudad de la Tele (TV City) in Tres Cantos, at Polígono Ar, 86. The production used the facilities for important interior sequences, allowing the crew to construct and control the hotel environments required for the story.
The complex covers around 22,000 square metres and includes roughly ten sound stages, giving the production plenty of room to build the dark interiors, rooms and other spaces needed for Basil's investigation. In other words, when the script called for another suspicious hotel room, the crew did not have to start hunting for one in the middle of Madrid.
Tres Cantos also makes sense as a production base because it sits within the wider Madrid film-production network while offering substantial studio space away from the centre of the capital.
For The Final Problem, that meant the filmmakers could create a convincing 1959 hotel environment indoors while keeping the visual world consistent across the series. The result is important for a story in which corridors, bedrooms and common areas become almost as significant as the people walking through them.
The production then moved towards Lloret de Mar in Catalonia, bringing the story's Spanish coastal atmosphere to life with one of the country's more visually distinctive seaside settings.
Lloret de Mar is known for its Mediterranean coastline, cliffs, beaches and landscaped historic sites, which makes it a particularly useful backdrop for a story supposedly taking place at a secluded hotel surrounded by water. It has plenty of scenery capable of looking beautiful one minute and vaguely ominous the next, which is practically a free production design department.
One of the most recognisable locations used for The Final Problem was the Gardens of Saint Clotilde, perched dramatically between Cala Boadella and Fenals Beach. The gardens are arranged on a cliff overlooking the Mediterranean and are known for their terraces, sculptures, stairways and carefully designed greenery. Their combination of formal landscaping and sea views gives the series a setting that can feel elegant without losing the slightly theatrical atmosphere expected from a classic murder mystery.
The production also filmed at Cala Sa Boadella, a picturesque coastal beach in Lloret de Mar. Its combination of rocky surroundings, Mediterranean water and relatively secluded character helped provide exterior material for the series. It is quite a contrast to the enclosed hotel interiors: outside, there is an enormous stretch of coastline; inside, thirteen guests are essentially left wondering who among them might be responsible for Elisa Mander's death. Holiday brochure versus murder mystery, then.
Another Lloret de Mar location was Casa Roviralta, situated close to the Gardens of Saint Clotilde. The historic property adds another architectural layer to the production and was used for both exterior and interior filming. Its distinctive appearance fits neatly with the period character of the series, helping the filmmakers avoid making every location feel like a modern-day Spanish setting with a few old-fashioned costumes thrown over the top.
The production also filmed in Toledo, the capital of the province of the same name. The historic city is one of Spain's most recognisable architectural locations, with a dense old quarter and centuries of surviving buildings that can lend considerable period character to screen productions. For a drama set in 1959, Toledo offers filmmakers plenty of visual texture without requiring the landscape to be heavily disguised. Even the streets have a tendency to look as though they already know they belong in a mystery.
Taken together, these locations give The Final Problem a much broader Spanish visual identity than its isolated-hotel premise might initially suggest. Madrid supplied the controlled studio environment, Tres Cantos provided the production infrastructure, while Lloret de Mar brought the Mediterranean coastline and dramatic gardens into the picture. Toledo added another layer of historic architecture. The clever part is that these locations can serve very different purposes while still fitting the same period world, allowing the series to feel expansive even when its central story is deliberately claustrophobic.
Lloret de Mar locations sound like the real scene-stealers. There is something amusing about using beautiful Mediterranean scenery for a story in which a group of wealthy-looking guests are trapped together and someone ends up dead. The Gardens of Saint Clotilde, in particular, have exactly the sort of grand, slightly theatrical quality that suits a mystery involving a retired Sherlock Holmes actor.
Madrid's studio work is obviously essential because nobody wants a detective drama where every suspicious conversation happens outdoors simply because the producers couldn't find a corridor. Toledo, meanwhile, adds that unmistakable historic Spanish atmosphere. Put everything together and the locations give the series plenty of character without overwhelming the actual mystery. Basically, Spain gets to look gorgeous while everyone in the story has a very bad time.
For viewers interested in The Final Problem filming locations, the production ultimately turns Spain into almost another character in the story, moving from controlled studio interiors in Madrid to the cliffs and beaches of Catalonia and the historic streets of Toledo.
