I and my boyfriend stayed at Carlos and Regina's place for two nights. The location of the house is extremely convenient because it is in front of the Clot metro station (L1) and there is a 24/7 open supermarket at the entrance. Even though it was very easy to check in to the house, we are little bit surprised because neither Carlos nor Regina was at home to welcome us and we were not informed about the situation. Instead of them, two of their friends introduced us to the house and we stayed together with them. The room was clean enough and the bed was comfortable but there was no lock on the door and there was no AC (there was a fan). If you want to stay in a place where you can easily reach public transportation, this is the place for you!
