The air bnb was great in every way except for the noise - it was advertised as "overlooking a quiet internal square", but in reality the traffic is loud, it overlooked a bar which was open late, there seemed to be a school (or something similar) across the road, the walls are thin within the apartment block and also building works were going on. Perhaps we stayed in the flat at a bad time so I'd like to give it the benefit of the doubt. It would be 5 stars otherwise but due to not being able to sleep I had to drop it a few stars as it was advertised as quiet. The flat is clean and apart from the noise, perfect for a city break as it is in a great location to walk around the corner and see the wonderful Sagrada Familia. Alex is also a great host and was always on call if we needed help with the metro and postal services. If noise isn't an issue for you, definitely go for this flat!
