I stayed in Sergios flat for 5 nights and had a great time! His nice flat was superclean, had everything I needed and looked exactly like on the photos. The location in Poble Nou is great (few to no tourists, close to the beach). Sergio was very responsive and helpful and even provided to sets of keys! There was no noise from the streets (Poble Nou is pretty quiet at night), but the walls are not very thick so I could hear the upstairs neighbors every now and then, but that didn't bother me really. All in all, I had a great stay and would recommend Sergio's place to everybody!
