This is a great place to stay in Buenos Aires. I made the reservation with Federico, but then Alejandra was the one to check us in and help us during the stay. Both of them are amazing hosts and were extremely helpful and responsive. A pleasure to deal with. I am originally from Argentina, and my sister lives 15mins walk from the apartment. We were visiting her since she was giving birth. The apartment was as described in the pictures: stylish and spacious. It has been recently renovated. My family and I stayed around 10 days and we had a blast. Kitchen was fully equipped and since we stayed long time this was very convenient. Also, it is a quiet place, so great to sleep. There are 2 elevators that work well.
The apartment is in well communicated area, transportation is close by to go every where in Buenos Aires. The area is safe, people are walking around until late at night, which makes it nicer to go out. Tons of bars and restaurants around and also many supermarkets. San Telmo market is next door (a bit pricy but nice to explore). San Telmo artisan fair is on Sundays, and if you like artisan stuff it is great to be right there!
I would totally recommend this place to anyone going to Buenos Aires!
