The photos accurately represent the space. It's clean. It's in a safe neighborhood. There is a flea market with cool shops across the street. There is a bar with good food and beer in that market. Next door to the building is a pizza place, a sandwich place (they specifically sell choripanes) and a small grocery store. It's near several bus lines, which really are super efficient in BA. You can get almost anywhere on the bus. Just note when you board you have to tell the bus driver "Hasta [insert neighborhood/landmark/address]" then you hold your SUBE card up to the scanner. The apartment is 15 min walking from the nearest Subte line.
The main downside if any is the street noise (mainly cars and busses passing by). I'm a heavy sleeper so I was not bothered. If you are a light sleeper, this is not a good place to stay. In fact, I would highly recommend you consider a hotel. Buenos Aires is a noisey city. There is nothing anyone can do about that.
All in all, great value and I would consider staying here again.
