The apartment is as in the pictures, very well thought and with everything that you need for a short stay in Madrid. It was very clean. And it is very well connected with the center.
The communication with Esther was good and fast.
The only negative thing was the noise; we were a bit unlucky with the neighbors and it was quite noisy during the weekend since they were a big group with several apartments partying; it is something that the host cannot control though; and currently there is a construction opposite the building, but this is temporary.
