Oliver's place was really cute and comfortable in a safe, calm, family neighbourhood. The Sarrià metro stop was a 7 minute walk so it was easy to get anywhere we wanted to explore. Several cute little restaurants nearby as well as late night bodegas with groceries if you arrive late. Oliver was very responsive and had a wine opener delivered when we couldn't find one! The only drawback was that you could hear every little sound from the street - the neighbourhood is pretty quiet for Barcelona but a regular volume conversation would wake me up, even with silicone earplugs. Just a heads up to other light sleepers, although I don't know if you'd find silence anywhere in the city. That being said, we would still return because everything else outweighed the interrupted sleep. Definitely leave yourself time to relax on the rooftop patio!
