Las Canitas is a beautiful, fun, neighborhood with many shops, restaurants and tree lined streets. There is a beautiful shopping mall called El Solar around the corner, as well. It is in close proximity to Palermo Hollywood and you can walk to the Subte D station to access the rest of the city.
The fifth floor apartment is very nice and cozy. There is a balcony, the A/C works well, the size is perfect for 1 person (maybe 2, but I usually travel alone)
