Elisa and Carlos were absolutely fantastic. Very helpful and accommodating when we needed to leave late on our checkout date! The apartment is very nice, large, open and close to all the sites, walkable to almost everywhere in buenos aires. The ac was great especially since it was very warm outside. There is a doorman at the building as well. The area is very nice and we felt very safe walking around at all hours. Would highly recommend to stay here for your trip to BA!
