Maria was a great host!, she was always in contact with me and was willing to help me with any question or inconvenient, the check in was a bit tricky since the system she had in place is no longer available/allowed, and there is a new system for self check-in, but this is just a minor thing in an overall great experience, the location is great, is near to most of the tourist places in Buenos Aires, the price is great, and the apartment is comfy, I would recommend it 100%
