Let me say I have been coming to Buenos Aires for years (2 or 3 times a year). I have stayed in numerous apartments and area's of the city.
This apartment is clean and safe (very safe) it is also very quiet. It is in close proximity to the pool, but I had my windows open and the pool noise never bothered me. The apartment is large, can handle 4 people easily (with the pull out couch). The building has a very nice pool and gym. the gym has lots of equipment but does get crowded if more than four people are in there at the same time.
The apartment is located in my favorite 5 or 10 block area of the city. I love walking around this area (very safe), lots of restaurants and cafe's in the area. Las Herras park a 5 minute walk is great to walk through, sit down read a book or just people watch ( however, like any large park in a major city be gone by 9:00 pm). But you can walk the streets near the apartment all night and have no problems.
The apartment is well located so you can take a bus, subway, taxi, Uber to anywhere you want to go. There is a super market, literally on the first floor of the building and a 24 hour super market 2 blocks away, along with a 24 hour Kiosko (mini 7-11) on the first floor of the building, just outside the guarded gated entry way.
There were a few issues with the air conditioner and hot water while I was there. However, after informing them of the situation a maintenance man was at the apartment with in a few hours to fix the issues.
