Very good communication; fast replies and helpful all the time.
Really got what we expected as read on descriptions and comments. I think it's expensive for what it is but it's a great area of Barcelona. Great for 1 or a couple (that is not too big - bed is quite small for two). Bathroom is literally in the room and pipes smell so...not the best perfume for the room.
Terrace is huge and in Barcelona weather can be really enjoyed.
If you are staying for a long period, make sure to ask to have the necessary supplies for it (toilet paper, kitchen paper, rubish bags, etc.) as we had to buy because we didn't have enough. I felt that there was a lot expected of the client (to leave everything clean, rubbish out when you leave, dishes clean etc.) but we didn't get the same when we arrived so...
Also important: it's the last floor of the building. We had some very windy days and there must be some air going through even if everything is closed because doors wouldn't stop knocking and, therefore, they made it difficult to sleep for light / sensitive sleepers like me...
