Antonio is a great host and a very kind person. I was never worried about potential issues with the place. There is an awesome Bodega a block away with the nicest owners. Next to the Bodega there is a small market that has been owned by the same family for three generations and the owners love talking to visitors. This place was a nice place to relax after all the hustle and bustle of our Barcelona adventures.
Barcelona is hot and humid in the summer and this place does not have AC, however there are ceiling fans, shades and windows in Antonio's house. So if you know how to cool a house down at night, it's manageable.
