We booked on very short notice for 5 nights and Luisa was immediate in her response and on all her communication.
The location of the apartment is great, with lots of restaurants, cafes and bars , as well as main sites, all in walking distance.
The apartment is lovely and comfortable with everything one needs. The windows are double insulated which kept most of the noise out during the Chueca weekends.
I would recommend this place for a short or long stay.
