My initial booking for another apartment was cancelled two weeks before I was due to arrive in Barcelona, but fortunately I was able to book this one on such short notice, and I was glad that this apartment and the hosts Blueground went above and beyond my expectations. The location is perfect, with a short walk to L4 and L5 metro stations, and several bus stops including the night bus services. The apartment is exactly as pictured, well-equipped, wifi was fast and the welcome package was a lovely touch. Like the other reviewer, I was a little hesitant about having to pick up my keys from a short distance away but communication with Blueground was extremely easy through their app and they offered an efficient solution to my worries. Noise insulation from outside could be improved but I came to accept this as part of the charm of living in an old Barcelona building :) Overall it was a wonderful stay and I will not hesitate to recommend Blueground and their apartments to my loved ones.
