I don't believe that Cesar's place should be on Airbnb. It is a typical low cost Spanish hostel that rents its rooms via Airbnb. You don't get the Airbnb experience. There is no interaction with the owners of the place.

The place is very well located near the Prado and within a very lively neighboorhood with a lot of interesting bars and restaurants.

My room was reasonably comfortable with a private bathroom. However, I had a hard time dealing with the lingering smell of a mixture of tobacco, cleaning solution and fried shrimp. The other negative was the fact that there was no hot water. When I complained about it, I was told that I was wrong and that in fact there was hot water. It was just a matter of leaving the tap on for a long time. Well, I left it running for 15 minutes and still no hot water.
