Apartment works fine. The host however was inflexible.
We needed to be checked in after 11pm. Pablo said this was impossible, and the listing mentions this (our mistake, we didnt see). But Pablo emphatically refused to help us and discarded any other possible alternative (e.g. leaving the key somewhere safe). His only option for us was we should come the next morning to pick up (basically, foregoing one day of our stay which we had paid for). Even when Airbnb customer service tried to mediate, he refused to find a middle-ground to help us, nor did he agree to let us cancel and get a refund (this was more than 1 week before the trip).
We had to get another hotel that first night. After being so inflexible about check in, imagine our frustration when he left the keys in a 24-hour pharmacy, which could have perfectly worked for the first night. When I asked him how come the keys could be left somewhere, he ignored my message and sent me tips for Madrid. Not cool, man.
