Things we loved: price, distance to Sagrada Familia, The Arch, we were able to walk to La Rambla in 25 minutes, we took a taxi for 15 minutes to Park Guell and the metro to Camp Nou.
The flat was airy, spacious, bright.
The shower was powerful.
What could have been better: there was no lock on the door of the bathroom. No problem for us and really a minor thing.
The double beds are foldable and slope to the middle significantly so me and my boyfriend kept sliding to the middle. This could have been more comfortable.
The street outside he house is not a very busy one but it was too loud to sleep with the windows open. Rubbish collection and other trucks made it too noisy. Luckily it was not too hot to sleep with the windows closed so we were fine.
Overall: we thought it was great value for money. With 4 of us needing 3 rooms it was so much cheaper than a hotel. The host, Ignasi, was lovely, he was super flexible in terms of letting us in and allowing us to stay beyond the check out time. We thought it was well worth what we'd paid for it and would definitely recommend it to friends.
