This unit is pretty good. The views are top notch and the unit was very clean. As mentioned in previous reviews, it's a little difficult to access (4 doors, an elevator, and a staircase), but I read these reviews beforehand and was aware of this going in. As a single traveler with only a small bag I didn't really have have a problem with that. My only minor issue was that the AC units drip condensation when running them full blast during the day. This is because the AC units are kind of old and Madrid is a frying pan in the summer. I just laid down some towels below and kept it from pooling. Besides that, the unit is a unique experience in a vibrant neighborhood. The owners are responsive and flexible (late check in after 7PM is 20 Euros). Thanks for the memorable stay!
