I'd recommend this place a million times just for the perfect hosts. Andrea and Ayelen were so accommodating and helpful that we felt safe and welcomed from before we even arrived!
On top of that, the location is great. It is close to the historical center, metro stops and buses that can bring you anywhere. Although metros are the preferred public transport option, we actually didn't take it once, opting for the buses that could bring us right to where we want to go and sight-see along the way. There's a laundry place just downstairs and plenty of supermarkets around. The apartment itself is spacious enough for 2, with a small but well equipped kitchen. We really felt like we had a nice home in the middle of BA!
