GUIX404 is the largest room with an en-suite bathroom on the first floor of Cal Guixater. The staircase to the first floor is accessible, spacious, and well-lit. The room is bright and features a high ceiling with original wooden beams, and the window has wooden louvre shutters on the outside. The rediscovered massive crossbeam gives the room a very rustic atmosphere. The floor consists of original *baldosas hidráulicas*, cleaned and polished, combined with dark wood paneling.
The room is simply and tastefully furnished with two ornate spindle beds with very comfortable mattresses and nightstands on both sides. There is room for a large Chesterfield sofa, and a wall cabinet provides ample storage space.
The en-suite bathroom was added by us and is very spacious. It includes a tiled walk-in shower, toilet, sink, storage space, and towels.
The lounge on the first floor is located in front of GUIX404. In the lounge, there are two different seating areas and a cabinet with books, games, and extra towels.
