Sary's apartment was wonderful, and the neighborhood is ideal! It's literally two doors down from the most popular bakery in the city (get the guava pastries at Rosetta), and is easily located to other neighborhoods.
As a matter of full disclosure, there was a slight issue with the water in the upstairs bathrooms, but I couldn't be more impressed with Sary's response. We returned to the Airbnb late, one night, and water to the upstairs sinks went out. Sary immediately responded (it was 2:30 in the morning!) and was working to fix the issue. By the time I woke up, she'd resolved the problem, and no showers or anything were disrupted.
I say the above to commend Sary on her response, and thank her for how prompt and diligent it was. Additionally, she was incredibly helpful with mundane asks (recommending the beautiful central post office, when I asked where we could mail a postcard).
Stay here, you'll have a great trip in a beautiful city!
