We stayed 4 days with Hector and was great. He's a very nice and smart guy, always smiling and listening good music. He let a list with some indications of where to eat and drink near the apartment and this gave us a beautiful and unique experience of Barcelona.
About the house: the room has a great bed, the bathroom was always clean and we could use the kitchen.
When I come back to Barcelona I already know where I and to stay.
