We thoroughly enjoyed staying at Andrea's apartment. The location was chosen by us as being close to several Tango studios and milongas to which we wanted to attend. Transport was easy as it was a few blocks to several subway locations and taxis were all nearby as well. The apartment was very functional for us as a couple who cook a lot on our own. Also, the apartment was quiet which was a real plus as BaS city living is normally quiet noisy (and something that non-city dwellers might not be used to). Everything is modern, clean and safe. Everything was accessible from supermarkets to neighborhood bakeries.
So we had a great time for the 2 weeks we stayed there and for the few issues/questions that arose, Andrea was very quick to respond.
