Nicole has always been very nice and friendly, she was already waiting for us at the apartment and gave us all the infos and the tips we needed. When we discovered that one of the two air conditioners didn't work, she let us buy a new fan and refunded the whole cost.
The flat is a bit small for 4 persons, however it's well equipped with all the necessary; maybe it's a bit hot for this summer season, as the sun stops for hours at the terrace, but we found it satisfying anyway.
The neighborhood is perfect, full of shops as supermakets, bar, groceries, and very close to Clot metro Station. Moreover, you can be to Sagrada Familia only with 10 minutes by foot.
We can obviously recommend Nicole and her flat!
