I spent a week in Ruben's apartment in Palermo, and it was definitely the best of the three Airbnbs I've stayed at in Buenos Aires. Check-in and check-out went smoothly, and Ruben was a gracious host, with good communication throughout my stay. The kitchen was a little small, but overall the whole apartment was very well-equipped. The balcony was a nice addition, and brought in a lot of natural light. Wifi and hot water were excellent, too. The building is quiet and safe, and the location is amazing - Everything you need is close by, including tons of restaurants, bars, cafes, supermarkets, and parks, and Bulnes subway station is a ten minute walk away. For what I paid, especially, it's a great budget option in an excellent area of Buenos Aires.
