Gabriel's place is well located within Madrid, and everything was clean and convenient. The unit is small, but is quite comfortable and the WiFi and AC work well. The building itself is dark at the entrance, and the unit is on the first floor next to the stairs. Neighbours in the building can be a bit noisy, and we were woken up once or twice by people walking up/down the stairwell and talking in the hallway. Gabriel was a bit short with us upon arrival, but he was otherwise responsive and helpful. Overall we were happy with our stay.
