We spent six nights in Madrid, and Jesús's studio was an excellent choice. It is small, but great for people who use it as a nice place to stay while visiting Madrid (or working for a short stay). All the facilities listed are working and inn good condition. The location is ideal for visitors, since it is right in the heart of downtown Madrid, at walking distance of very many "Madrid's musts", and with excellent access to all sorts of transportation (subway, buses or taxis).
We did not get to meet Jesús for he has a busy schedule and we were out getting to see and feel lovely Madrid, but we spoke on the phone several times, for Jesús wanted to make sure everything was well and checking if we needed anything. A most welcoming host.
In all, highly recommended.
