Carolina's place was really comfortable, cozy, and quiet! It was beyond easy to access the rest of the city: a 5-15-minute walk to the main "touristy" places in the city, 5-10 minutes to the subways (and many buses are right outside or a block away). Carolina also was kind enough to let me leave my backpack there before. If it matters to you, hot water and pressure was instant and consistent, and it stayed warm in the Argentinian winter, even without the heater.
Tiny things are that it doesn't have a microwave and the showerhead has a tendency to spray outside the shower--make sure you don't leave anything on the floor in the bathroom and probably best to turn the showerhead to the left--but beyond that...it was the best AirBnB I've been to in the three countries I've been to on this trip, and definitely the best value!
