We had a perfect stay. The host was very flexible regarding checking in- and out (i.e. he allowed us to check out at the end of the day). The apartment has all the facilities required and is in the center of Malasaña, which is a very trendy part of Madrid. No noise at night though. The host also provided us with good tips for eating and drinking out. In case of another visit to Madrid, we will definitely come back here.
