The apartment was beautiful, well appointed and spotlessly clean. We were allowed to drop our bags before check-in time, which helped enormously and Juan Carlos was very welcoming on our arrival. The location was great in terms of being walkable to most of the things we wanted to do, plus there were lots of restaurants and an underground station nearby. The flipside was the street was pretty noisy, this didn't matter during the day but we were woken 1-3 times a night by drunk people yelling despite the bedroom being at the back of the flat. The noise in the living room was definitely worse than in the bedroom, so the sofa bed is probably only ok for the heaviest of sleepers! Also, whilst the bed in the bedroom was divinely comfy, the sofa bed (as many are) was pretty hard. Overall despite these things we had an amazing time in Barcelona, and the apartment was key to that!
