We spent 6 days in this flat with my family (wife and 2 kids).
This flat is really nice. It is VERY well-located, close to subte Las Heras, the Recoleta cementery and some of the nicest places in this wonderful city. The flat is spacious, well-decorated and with a beautiful backyard that we enjoyed to read and to rest some days. It was also clean and well-kept. There are two minor points that should be addressed, however.
First, the small bathroom´s sink was not working, which was quite uncomfortably for all. Second, the master bedroom´s bed was too narrow for a couple to use comfortably, which is a shame, and it affected my sleep. Indeed, I had to move a couple of days to the othe room when I needed to sleep properly. Apart from that, everything was perfect.
