Nestor is one of THE best superhosts I have ever experienced. His place is so beautiful with some beautiful art all thoughout his home. It is in the perfect location to walk or take a short bus ride to anywhere you want to visit. Not to mention the bus stop is right in front of his place. The room I stayed in had an air conditioner which was key due to the heat in August. He made me feel so welcome from the moment he opened the door to his humble abode. I highly suggest staying here if you plan on visiting Barcelona!
Also, the view from the room was so nice to wake up to. I will be staying here the next time I come to visit.
