I’m afraid I am struggling to understand some of the good reviews here. The flat and its interior are quite simple given the price per night. It also takes about 30 mins to go to La Rambla/Gràcia area etc.
It seems that the flat is not run by a private host, but is a service apartment building run by a company. We were pointed by the host to the company’s office for check in. I contacted the host a few days before arrival that we have an evening flight leaving Barcelona and confirmed that we can leave our luggage in the office. We confirmed this again at check in with the lady in the office. On the day we were leaving, the office was closed when we went to leave our luggage. We called the number Maria gave us, and it didn’t go through to her but went to a call centre. A guy from the call centre told us the office is closed for the whole day and we couldn’t leave luggage anywhere. The attitude was unhelpful. We ended up dragging our suitcases onto the beach all day. The experience and the way of communication is disappointing.
