Carlos's flat was great. Very spacious even for more than 3 people and very clean. ALSO, THE BEDS ARE SO COMFORTABLE; it felt like staying at a nice hotel. Carlos was extremely responsive to messages before and during our stay, was flexible with check-in/out, and made himself available to any questions or needs we had during our stay. I couldn't recommend enough! My family (who normally do not "do" Airbnb's) was extremely impressed as well with both the flat and host. Would definitely stay again next time I'm in BA.
