Everything was perfect, good accessibility also by phone. Check in and check out was smooth and uncomplicated. For the check in we met with an employee in front of the accommodation. The flat was super clean, the beds very comfortable and there were enough towels available. The walls are a bit thin but the neighbourhood was very quiet. If you are a light sleeper you should take earplugs to be on the safe side as I think thin walls are common in Barcelona/Spain. I would definitely choose this Airbnb again for my next trip to Barcelona!
