The studio appartment is very convenient. It is well located in the center of Madrid, close to almost everything you wish to see on a short trip.
The apartment is exactly like the photos, it is very comfortable for a small stay and it was very clean. It is not very big, yet we had everything we needed.
Mari Paz and her sister were very nice before and during the stay and they were very adaptable even if we arrived quite late at night.
The only thing that could disturb you is that the building is a little bit noisy, so if you are a light sleeper it can be annoying.
