I never write reviews but this flat and whole experience was great. I stayed for over two months.
Every detail carefully thought out. Every question I had kindly answered within an hour or two - even on weekends. That doesn't happen in Barcelona!!! Not the cheapest option, but worth it.
The flat is super quiet for sleeping, very comfortable bed, and, the little terrace gets direct sun in the afternoon :)
Negatives? The shower is small, but, it's brand new and nice and not really an issue.
