This is on a very quiet, residential neighborhood that was pleasant to be on and walk around in. I would stay in this same neighborhood again and very much enjoyed Gustavo's place. I highly recommend it. I enjoyed having pastries and coffee I got to-go on the balcony in the morning and slept like a baby in the quiet.
The only advice I'd have for people who come to stay is to bring a map and use it to get around. DO NOT have your phone out on the street, for any reason, not even GPS. I was using mine for GPS when a motochurro robbed me of it (grabbed it from my hand) when I got turned around while walking down Av. Pueyrredon (between Pena and Barrientos streets). A few days later I was walking in the same general area (Charcas and Guise) and saw a two-person motorchurro team steal another woman's phone out of her hand as well.
Gustavo was incredibly helpful and accommodating throughout for both my flight issues and then the theft. I was very appreciative.
