We thoroughly enjoyed our stay at Antonio's apartment. It is spacious and full of character, beautifully decorated and in a great neighbourhood - close enough to the main sights and quiet enough that one feels away from the tourist hustle in the Ramblas and downtown. We didn't meet Antonio in person but he was very responsive via email and the check in process went smoothly as we got greeted by Florencia who let us in even as we got delayed due to traffic entering Barcelona. Would definitely return next time we're visiting!
