Short review: I would definitely stay here again. Miguel and Rosa are awesome hosts and the apartment is really nice.
Long review: When we arrived there were fresh fruits, wine, and an assortment of crackers and breads waiting for us. Using a map, Miguel took the time to get us oriented with the city and gave us pointers where to visit and where to eat. Also, we checked out on Oct 1st 2017, when Catalan was voting for independence from Spain. We didn't know what to expect but Miguel took us to the airport early in the morning because we were expecting protests, blockades, potential violence, etc. All of those occurred and Miguel helped us avoid those issues, which was amazing customer service from Miguel.
The place is really nice and has everything you need to be comfortable. The location is close to restaurants and public transportation.
