Staying at Camilo's was my first Airbnb experience, but I didn't get disappointed. He was really friendly and welcoming. During the whole stay I never felt uncomfortable at his house.
The room, bathroom and kitchen looked exactly like on the pictures. The bedroom is really spacious, clean and offers a great view from the balcony to the Sagrada Familia.
The only thing I would suggest to change is the fact that the room can't be locked. As there were other people than Camilo too in the apartment, who could get in the room easily.

All in all I believe that Camilo offers a great-value-for-your-money, especially because his apartment is centrally located.
