I was a first time air bnb'er and very nervous about attempting it as a female traveller. I had debated staying in a hotel instead of an air bnb.
But Carlos was fabulous and put me at ease very quickly. His place was exactly as described and he was extremely helpful when asked. He even went above and beyond by getting me to a location that I was unsure how to get too.
I have told him if I return to Buenos Aires I would stay at his air bnb again, without hesitation.
I enjoyed the feeling of being in a home away from home, that you can't get in a hotel, and I felt very safe. Those were my prime worries as a first time air bnb'er.
I highly recommend Carlos air bnb.
