Stayed for a little under a week. As our first time in Madrid, the location is unbeatable. Far enough away from the “super” touristy area to explore Madrid; yet, it was close enough to still be a tourist and enjoy the museums, restaurants, and bars. The farthest away we had to walk was about 25 minutes to Plaza de Alonso Martinez.
The room was very clean, and looked just like the photo. The fresh air from the bathroom window in the morning was amazing (not sure how to explain it, but I can tell it was cleaned meticulously).
The only issue was the air conditioning unit. While it worked and was very strong, it leaked profusely. The first two nights I woke up in the middle of the night to clean up the water spills and ended up using a pot and rags to catch it. I let the host know, but she didn’t respond to that notification. Also, make sure it has full batteries or else it is a pain to turn on and off and to adjust the settings.
Another note, the walls are extremely thin. Some nights, when the outside AC units of neighboring apartments are on, it makes a very loud rattling sound. We could also hear people speaking and leaving and entering the building. I didn’t mind it, but if you are a light sleeper, beware.
Overall I loved the stay and would return.
