Christophe has a great apartment in a great neighborhood in Barcelona. He was very welcoming, and provided us with lots of tips of places to go see, places to eat, and things to do. The apartment is kept very clean, and the private area is spacious. Apollo (the cat) is quite playful and curious, so if you are not a cat person I would suggest keeping the door to your room shut. We found him quite entertaining though.
I would recommend staying with Christophe, and we hope to be back soon.
