I spent two months and half in this appartement, for an academic exchange. The flat is nicely located, with a few convenient store around, some good restaurants (Bonnie&clyde burgers are amazing), public transportation are pretty close too. Concerning the security, there is usually someone supervising the building, or somebody at the entrance.
The appartement is wholly conform to the pictures, the balcony has a nice view, I have nothing to say more, I spent an amazing experience in Buenos Aires, kind of movemented because of the covid-19 but I will be back for sure.
