My daughter and I really enjoyed the apartment. We felt so blessed to have been able to stay there. We were amazed at how central the apartment is to everything we wanted to do. It was easy to walk to so many places and easy to jump on the metro as well. We have friends travelling to Barcelona in October and have recommended the apartment.
Here's the best part, the apartment is right off La Ramblas which is very lively and a bit noisy. You can hear some of the noise from the front room in the apartment. But as soon as you go to the back of the apartment where the rooms are located, it is very quiet. The best of both worlds.
We had a magical time in Barcelona and much of that had to do with the lovely accommodations.
Note: We used bizflat's services for airport transportation and that was really helpful too (Mercedes husband runs BizFlats).
