Andrea's place was very nice and located in a great, safe location. There are great cafes just up the street and parks nearby. If you're a walker, you can walk up Ave Santa Fe and get to the heart of Buenos Aires.
She was very helpful in showing me the neighborhood, bought some fruit snacks, and booked my ride to the airport. She's more than willing and available to help. Super sweet lady.
The bed is comfy, you get your own half bathroom, and access in and out of the building was easy. The AC broke down while I was there and she ordered a new one in days.
I recommend her place highly.
