I am really happy I chose Roberto's place to call home for my 5 weeks in Buenos Aires. My favorite thing about the place was how spacious it is: a large living room and kitchen, two bedrooms, and plenty of outdoor space. It is also very private, including the large rooftop terrace. It is also a short walk from so many nice bars, restaurants, and shops in Palermo Soho and Hollywood.
There were just a couple things I did not like about the location. There is a bar across the street that was pretty loud many nights. Also, the nearest train station is a healthy 15-20 min walk away - but there are many buses closer.
Overall, I would definitely choose Roberto's place to be my home in BsAs again!
