We had a good stay in the flat. The location is excellent for exploring the city, the most important sights are available on a 15-minute walk. The flat is close to the metro station of Gran Via, making it easy to reach by metro as well.
The flat is a lot smaller than it looks on the photos. When the sofa bed is unfolded, it is impossible to move through the living room. Limited equipment in terms of glasses/crockery. Bathrooms were not very clean. Lock to open the front door of the building works with difficulty. Luxme was responsive to resolve issues.
