Great place to stay in Buenos Aires! We stayed there only for a weekend but it was everything what we were looking for. The location is in the nicest district of Buenos and walkable to places of interest. We travelled with a one year old and we had a crib setup in the room. I also appreciate that the bed was big so our little one could easily sleep with us as well. The place was super clean and the host was very friendly with clear instructions.
The apartment is on the main street so you can hear occasional sirens at night. However together with a kid we were able to sleep with no problems.
