I thoroughly enjoyed the month I spent working from and living in Maria's apartment. The apartment was clean, spacious and perfect to work from. Maria provided me with a large desk and the wifi was great.
It's walking distance to the metro which takes you into central BCN in 25 mins. Very safe residential area with cafe's and a shopping center in walking distance.
Maria was a great help to me advising what I should see and do, and was always available by text. I would highly recommend her apartment for your stay.
