It’s very very clean and perfect distance from the heart of Madrid. Everything is walking distance to touristy locations. There are three keys to enter the location providing peace of mind for your belongings and security. The heaters are very small and don’t really heat up the apartment but if you leave one on all night with the door closed in a bedroom it’s bearable. The internet was a big issue and disconnected often or wouldn’t connect at all but we didn’t do our part in contacting the host since we were out all the time anyways.
