Everything was really good and I recommend this place for many reasons: location, cleanness, communication, check-in and chek-out, the nice architecture of the flat. However, for me, but this is my personal view on how to use Airbnb, when I booked the flat, I had the impression from the description that the flat was privately managed by two girls, Mireia and Maria. I generally don't book apartments from agencies because I like Airbnb to be used for its genuine first purpose: which is to open your own home to guests. The place was lovely but I was a bit disappointed when I understood that there was a company behind that which means that the apartment is a bit impersonal and has never been lived by the real owner. But again this is my personal view on how to use Airbnb, some people may instead prefer that way. Thus, I would only recommend to the host to write clearly that the real host is Barcelona4Season. The rest was all very good.
