If you go to Barcelona, I really recommend you this apartment in Gràcia. I stayed there for 4 months and I really liked the apartment. It is huge, you have a lot of space and even an office and a balcony. Each week, Pedro came and cleaned some of the shared area. Everything was exactly as it was described and shown on Airbnb. The communication with Rosa & Olga went very smoothly - they always answered within some hours. All in all, it was a great experience and I would go back there if I went another time :)
