This apartment is well located. It is also clean, large enough for a family and reasonably well stocked. We found the owners, Nikolas and Pilar, easy to communicate with while we were there through the Air B&B app.
What I would caution a family with small children are the amount of rules this apartment has (absolute silence and a decibel monitor/noise monitor in the apartment) and I have never experienced this on Air B&B or at another apartment in Buenos Aires. My husband is from Buenos Aires and we frequently rent apartments when we visit. We were traveling with our 15 and 16 year old boys who knew the rules and were not loud or disrespectful. Despite this, we came in one night after dinner at 11pm and someone called our apartment on the building phone and told us to take our shoes off when we walked! Mind you, you almost can’t eat dinner in Buenos Aires prior to 10pm. A few nights later the people on the bottom floor with a patio had a loud party until 2am. I would be afraid if I had young children who ran up and down the halls or cried this would be a constant issue. If you come to the city of course you should be respectful but you also feel at home when you are in the apartment. I went back and forth on whether to give this 4 or five stars. I ultimately decided on five stars because the rules were disclosed to us but the rules are many and we found then over the top. Otherwise, the apartment was great.
