This is a nice apartment. I highly recommend it.
The apartment was clean and well decorated. The bed and other furniture were comfortable. There was plenty of hot water, and the internet was fast and reliable. The appliances all work great. The kitchen was stocked with pots & pans and utensils to enable cooking at home for a long stay.
It was a very safe neighborhood. Grocery stores and restaurants are a short walk nearby. There are several bus stops a few blocks away. It is easy and inexpensive (42ars bus, 600-1000ars uber) to get most places in BA. There is some street noise, but it's not terrible.
Pia is a kind and thoughtful host. She was always very quick to respond and very helpful. The apartment has two air conditioning units. Unfortunately, one broke. Pia had it replaced immediately.
