Theo is a great, kind host and welcomed us when we arrived at the apartment. He gave us useful tips on the area and answered any questions we had. His apartment is clean, with great amenities therefore we did not need anything. The location is very convenient and close to the metro station. We pretty much walked to all the major Barcelona attractions (most were between 45 min to 1 hour) and only took the metro once. I also very much appreciated the quietness of the location. I would recommend staying at his apartment!
