This place is just okay. The apartment could use a deep clean, and while the furnishings are cool, the apartment itself is more rundown than it looks in photos. I'd recommend this apartment for anyone doing a quick stop in Madrid for a few nights that just needs a place to sleep. I wouldn't recommend it for anyone who needs to work remotely or use the kitchen, as the place isn't ideal for that kind of stay.
Other than that, the location is fantastic. And the host is quick to respond to requests.
