Communication with the host was a little terse--perhaps he is a busy guy!--but basically adequate. There was a little confusion about the check-in, namely that the room was ready, but it was not clear how to enter the listing upon arrival. Jose's listing was as described on the website, and there is a kitchen and washing machine available for guests' use. Jose and his cleaners do a great job keeping the common spaces clean (in case it is not clear from the listing, it is a shared apartment space, so the bathroom and kitchen are shared by the guests staying in the 3 bedrooms). Guests might bring a small padlock for the bedroom doors, but at no time did I feel unsafe there or worry about my things.
The location is fantastic, right in the heart of Madrid, so if you don't mind walking, you don't really need to use the metro or buses to get around the city. However, there are several subway stations nearby in case you need to use them. The area is very lively, but there is no noise in the back rooms (I cannot speak for the room facing the street). I would stay here again, 5/5 stars. Thank you, Jose!!!
