I had 6 beautiful days in Buenos Aires. Palermo is very nice and safe neighbourhood. Apartment is located in a nice area, building is safe, easy to find, easy to walk around, take a bus, metro and pick up a cab. It's very cozy and it has all that you need. Mario is a great host, he gave me fantastic tips where to eat (best chorizo in the world and entraña), where to do my laundry, and basically he was always quick to answer to any question. I recommend the place and the owner. Definitely you should take a hop-on hop-off bus which gives you a fabulous view, from Bomboniera in Boca to River Plate and Palermo. Muchísimas gracias.
