This place is in my opinion THE BEST LOCATION IN BUENOS AIRES! It is very close to a ton of bus lines, the metro system, taxis, entertainment, places to eat, wineries, places to send faxes/scan documents, pharmacies, supermarkets and even has a farmer's market on Sundays. If one needs a point for a hotel to be pick up for tour, the building is located diagonal to a hotel. Everything is within walking distance!
I was a bit concerned about the neighborhood, but although no pretty as Recoleta or Palermo, due to name of the neighborhood, but because it is sooo close to the Congress building, the is very good surveillance. At the plaza in a summer night it seems like all the city is cooling off at the plaza. You see some homeless people, but also families and couples spending time and getting some relief from the heat.
The apartment is not modern by any stretch of the imagination. In my opinion, the title should be "Retro Chic", since the place has character, but the appliances, except for the T.V and the refrigerator are very outdated and difficult to use at times. That would make difficult for someone who plans to use the kitchen a lot, even though it is fairly equipped. The A.C. in the bedroom ( indispensable in the Summer) is very noisy. I think the description of the apartment should mention that daily there is some mechanical noise coming through the bathroom from the building next door. So if you plan to sleep until late in the morning that could be annoying.
In addition, Martin provides the information for the superintendent of the building. His name is Eduardo. Eduardo is very helpful and knows the neighborhood very well. You can ask him anything and he will be glad to give you information.
