This apartment is located in a perfect spot for exploring the city. We were 5 adults and there is plenty of room to accommodate all of us. The apartment is surprisingly quiet situated on a busy street. Juan responds promptly to emails and informed us we would meet with Joan (John) who would show us the place. Joan was running a couple of minutes later but he reached out to me immediately and was only delayed about 5 minutes. It was very easy to communicate with Joan and Juan and they were available for any questions.
I highly recommend this location to anyone planning a few days or longer in Barcelona.
