Barracas is a great location to move around Buenos Aires. There are several bus options available and Maria's place is close to several restaurants and a grocery store.
The apartment was really wonderful! We great enjoyed our stay and took advantage of the roof-top pool.
Water pressure is great, bed was super comfortable, and it is well decorated. For a studio apartment, we felt we had enough space to move around.
I highly recommend staying at Maria's place! It was our favorite Airbnb during our stay in Argentina.
