Had a lovely stay at Osvaldo's place. The apartment was clean and had every thing one would need. It is definitely in a lively area, with lots of music and parties. Osvaldo's communication was great and he was super helpful. Check-in and check-out were easy and smooth. The laundry facility in the building is a nice added benefit, though it requires 12-100 peso coins for each load. The Bellavista neighborhood has a lot of restaurants and bars, and is about a 20-30 walk to downtown.
