We stayed at Ulises's place twice while passing through Madrid during our trip to Spain. The apartment is small but exactly as pictured, nice, clean, no issues. Location is unbeatable. We loved that we could get to great restaurants and tapas bars within 5 minutes walking from the apartment - very convenient! El Rastro is right outside the apartment on Sundays which is cool too, and you are just steps from Calle Cava Baja which is a great place to go out and do a tapas / bar crawl :) The only downside is that if you have a late flight on your departure day Ulises charges extra fees to store your luggage even if only for a few hours. But other than that, we had a great stay and the apartment and location are both great.
