Gema's place is great! The apartment is super cozy and very functional. It has a little yard perfect for having breakfast or eating outside. Because it is far from the street is quiet. The corridor that brings to the apartment is beautiful!
The location is very practical for moving around Buenos Aires, and the neighborhood is well-served.
We did not meet Gema but she was very available and we could do an early check-in, which was very practical because we arrived in the morning. However, consider that you might be charged for that by the person who receives you.
