Staying at Max's apartment was great. Max is a kind host, replied super fast, gave us lots of tips and had all kinds of maps and guides available for us. The apartment is ideally located and you can walk everywhere. Lots of bars and supermarkets in the area. The apartment is cute and we were able to cook every day. Just be aware that if you are my height (1,82 cm) you won't be to stand in the bedroom and you have to you won't be able to wash your hair standing up in the shower. For a couple of days, that was not a problem. Enjoy Madrid!
