We had an excellent stay (4 nights) at Isabel's place. It was our first experience with AirBnB, and what an awesome experience! Isabel was very kind and easy to communicate with right from the start, and she was also very accomodating.
The studio is just like in the pictures: clean, modern, cozy, and romantic. The bed was comfortable, the air conditioning system worked flawlessly and we slept so well that we woke up later than expected most of the time.
We cooked often as the kitchen was fully furnished, and ate outside everyday on the lovely private terrace, which offers a shaded dining area surrounded by trees and flowers. Really picturesque!
The location is very nice as the studio is situated in a quiet neighborhood, 5 minutes by walk to Park Guell and about 10 minutes to the Alfons X metro station, which is very convenient (best metro line to visit all the hot spots in town).
We had a wonderful stay, so we highly recommend Isabel and her apartment. You can book without hesitation, you will not be disappointed! A++
