We stayed with Marina for a week. She was the nicest, most welcoming and flexible host we had in airbnbs. She helped us with everything, gave us tips and frequently asked how we feel. The apartment was clean and nice, no complaints here. It’s located a little outside of the center, but you can walk 20-30' or go by public transport (bus/metro). Proximity of Parc Güell is nice though. One thing that bothered us was the room's air conditioning device that did practically nothing, so the room was much hotter than the rest of the apartment. But this little inconvenience didn't destroy our stay. I recommend Marina's place 😍
