Unfortunately I didn't have meet Oscar personally, but his extremely friendly father has welcomed me. During my stay we connected with Oscar via airbnb messages and received quick response to all my questions. The apartment is perfect, its exactly the same as in the pictures, very bright, clean and spacious. There was everything I needed during my stay and even more, it was great experience. Apartment location in a center of Barcelona, in walking distance to Catalonia square and Gothic quarter with great neighborhood and chance to explore the city by your feet. In case I will come to Barcelona again I will definitely stay in Oscar's apartment and will recommend it to all my friends.
