Terrific place for BA city trip. I had a 1 week stay in the apt, situated in a great area just around the Recoleta Cemetary & Recoleta Mall. Main (shopping)streets like Santa Fe are in walking distance. Public transport in front of apt (busses) or less than 10 min walk (Subte). Daily groceries, internet cafe (locutorio), bank, bar/restaurant is all right in front of the apt.
The apt itself is more than ok. It's on the 5th level (of 13), spacious and well equipped. It felt like my home in BA for a week. Marcelo and Tiffy were abroad during my stay, but even on their holiday stayed in touch with me via email.
I enjoyed my stay in BA and this apt very much. If you consider to visit BA and look for a nice place from where you can start your daily explorations, I strongly recommend this apt!
