Gus is an amazing host! super quick to respond to messages and flexible with check in and check out when possible. We stayed 5-6 nights at Gustavo's and it was a really good time! We found the studio-apartment very clean, spacious for the two of us and our many suitcases and with all the amenities you could need! It felt like we were in an apart hotel :) It's well located, there are many great restaurants nearby ranging from all cuisines. Gus also arranged for a car service to take us back to the airport which was great! I would most definitely stay at Gustavo's again when visiting Buenos Aires!
