Staying at Camillo's place was OK. The room is really basic, it has a fan but it didn't help much because it was really hot..and although the room has a balcony, it's quite noisy from the cars on the street that go by from early morning. The bathroom was basic as well but everything was clean.
We had good communication with the host and he stayed up until 1am to welcome us in the flat since our flight arrived quite late. Both Camillo and his roomate are nice people but they really stick to the house rules, so be sure to read them in detail. The neigborhood is OK, quite touristic because of the Sagrada Familia but there is public transport quite near the flat. All in all, it was an OK-value-for-money stay.
