I was extremely happy with my choice staying at this studio in Palmero. The room is really well layed out and has a good amount of space to relax. The shower has good powerful hot water. Access to the building is all codes and a card for your room, I found this really useful and I believe there is a card/key locker next to the studio now.
This is the area to stay in while in Buenos Aires. There are alot of bars, restraunts and cafes nearby and the public transport is really easy and cheap.
