Rafael and Tania are always super responsive and very helpful. We got everything we need. They also gave us directions to the local attractions and helped us book the taxi going to the airport. The apartment is very spacious, and at a super convenient location. Park Guell, La Sagrada Familia, Casa Batllo etc are all within walking distance. La Barcelonena is only a short metro ride away, and the metro station is within a few steps. There are a few cafes, a small super market and bars just a few steps away, we enjoyed the breakfasts from the cafe downstairs and tapas from a bar at the corner. The master bedroom is facing the street and can sometimes be a bit noisy if you leave the window open. But it didn't bother us, there is AC and you can close the windows.
Will definitely rent the unit again if we have a chance to come back to Barcelona. Will recommend it to all our friends!
