Luisa's apartment was great! It was very clean, well stocked and comfortable. My flight to Madrid arrived in the morning and Luisa arranged for her father to meet me at the apartment for an early check in. I could not have been happier. My only problem during the entire stay was that I could not figure out how to use the modern induction stove top, but that was due to my silly inexperience (It worked perfectly).
The apartment is on a street with lots of pedestrian traffic and near busy Chueca Plaza, but at night I closed the windows, turned on the AC fan on low and the street noise disappeared.
Luisa was easy to work with and promptly responded to all questions. I would definitely recommend Luisa's apartment.
