Gustavo's place is of great value, very clean, and located in one of the nicest neighborhoods in Buenos Aires. The apartment is on a residential street with public transportation (trains and busses) just a 5 minute walk away, along with plenty of places to eat and shop. The apartment is very spacious and open; it's furnished with a queen sized bed and a full sized pull out bed from the couch in the living room that becomes the kitchen. The balcony- and access to a washer and dryer- are very nice bonuses that make the stay that much more worthwhile for the traveler.
You get to live like a local in Gustavo's place and as it's located in one of the nicest and most lively neighborhoods in BA, my stay reminded me of living in some of the more beautiful neighborhoods in New York City. Would highly recommend.
