I stayed more than a month in the apartment. It suited my needs very well. Did some work including video calls without problems.
The gems of the place very to me is the big terrace that is blessed with light from morning until sometime mid afternoon. This fitted my schedule perfectly. It is also very close to big green parks and green areas where you can go for runs, so outdoor exercise etc. or just enjoy the very beautiful buildings in the neighbourhood.
It is located close to two central streets that can be noisy with the terrace door open. It wasn’t an issue to me, and with the door close it wasn’t and issue at all.
Within 30 minutes walking distance of most places. Even less if you bike around (Ecobici works great). The location made it easy for me to explore the variety of Buenos Aires most central areas and popular sights. The hosts are great - fun, helpful and easy to communicate with.
