I had a great stay in the apartment of Constanza. The apartment is just like on the pictures. It's a very light and clean place. The kitchen is small but offers you the right equipment you need for a short stay.
The neighborhood is full of restaurants, cafe's, etc. There is a very nice atmosphere, I felt completely safe.
Communication with Constanza was perfect. She reacted immediately on my questions and where needed she helped me out.
The subway is 6 blocks from the apartment and brings you to where ever you want in Buenos Aires.
I had a very nice stay and would definitely recommend this apartment.
