I stayed for 5 days in Oscar's apartment, and I have to say it was all I was expecting. The location is extremely convenient; walking distance to many places and attractions. There are plenty of places where to eat quickly, like a Bakery just in front fo the building, with very artesanal products. Also there are a very nice Pizza Place one block from the apartment, and also some choices where to go to buy groceries.
The apartment has a very nice Terrace, with a very nice view.
The building is very clean, and the few pleople I saw at the elevator and common area, were very nice.
At the end of my trip, and forgot a couple of things in Oscar's apartment, and he was so kind that he brought them personally to me.
I reccomend this place for anyone who wants to visit Buenos Aires.
