This place is very beautiful and clean. It is set up like a hotel. Everything was newly renovated. Very spacious for European housing. Washroom was very clean and big. It was equipped with a washer. The air in Madrid was really dry during my stay (early August) so most clothing dries quickly overnight.
However, it is quite far from the airport. It requires three separate subways and a bit of walking - totalling 1h 25 mins. The home is not located in the main streets. I travelled with my boyfriend, but I would not feel comfortable walking home by myself in the evenings as a solo female traveller.
