Unfortunately, the stay in the apartment was very unpleasant for us. For starters, the air conditioners are not workin and the portable AC devices didn't do a good job at all, it's not real air conditioning and they make a lot of laud noise. It was very hot at night. In addition, there was a very loud noise from the neighbors in the building, which are also related to the same apartment owner.
Both things did not allow us to sleep at all and made our stay in Barcelona unpleasant.
