I honestly can't say enough about how much my family and I enjoyed staying at Robert's casita. It is architecturally stunning and seamlessly blends amazing indoor and outdoor spaces. My dad sat on the upper terrace every single morning for a month drinking his coffee and watching the sunrise.
The location is pretty ideal. It's several blocks from the main tourist center in a far enough/close enough balance meaning you're not caught up in the occasional tourist throng and have the major plus of being in a true neighborhood where everyone greets one another each morning with a hearty "buenos días!" It's also only one block from one of the best local markets in the city (hands down best tamales, atole, and fresh produce you can find).
Check in was a breeze, and Amado (the house manager) was always available by text/phone for anything big or small. Luz (the housekeeper) comes once a week and does a great job, topped off with replacing all the fresh flowers on the first floor.
The beds are comfy, there are plenty of towels and other necessities, and the kitchen is the perfect place for you to practice your mastery of delicious Oaxacan cuisine.
Can't wait to go back!
