The appartment is very central, with many buslines stopping just meters away, and supermarkets, shopping mall, cinema, restaurants/cafees, recoleta cementary within some minutes walking distance.
We were 4 persons (2 adults/2children) staying in the appartment for 2 weeks and found the size convenient. Kitchen is basic, but ok for breakfast and cooking of small dishes. Furthermore we found the appartment clean and tidy with more than enough space to store luggage and belongings. It is in a very safe building and the neighbours are all very friendly and helpful.
Graciela responded very very quick on all our questions and Sergio/ Maria Laura helped us a lot with practical things.
Be aware that the appartment is not completely silent, although situated on the 8th floor. We found it hard to sit out on the balcony and have a conversation because of the traffic. Inside, with windows closed it was silent enought though.
All in all a good value appartment and a good choice for Buenos Aires. We really enjoyed our stay at Gracielas place and hope to come back another time!
