Alex and his girlfriend are very nice, friendly, communicative and always ready to help. The room as well as other parts of the apartment were clean and comfortable. The location of this accommodation is not in the main center of the city, but close enough to walk or take the bus (bus stations right in front of the house). Right next by is Parc de la Ciutadella - for me and my girlfriend surely the most beautiful park in the city.
Overall we didn't miss anything and had a great time in Barcelona. We highly recommend to stay at Alex's place.
