I staid in the apartment with two friends and we found it cute, confortable, clean and well equipped. We didn't meet Sergio, but just his girlfriend and they were both very nice. The apartment is in an excellent location in Lavapies. This barrios is in the center of Madrid: It is walking distance to every thing you need and want to see and near all the transports you need, but it is not in the area full of turists. According to us it is a fantastic apartment, so we reccomend it to all people !
