I had an excellent stay at Anita's place in Mexico City. It's definitely one of the best stays I'd had with AirBnB. I'll list some of the points below.
1. Great location - Her place is right next to the MetroBus line and 5 minutes walk to the nearest subway station. You can also walk about 15 minutes north and be in Zona Rosa, which has lots of shops and restaurants. If you walk 3 minutes west you'll be in Parque Mexico, which has lots of trees and is surrounded by nice restaurants.
2. Knowledgeable host - Anita can speak Mandarin Chinese, Spanish, and English fluently. Check-in instructions were communicated clearly and went without a hitch. As a former tour guide, she is very welcoming and knowledgeable about things to do, see, and eat in Mexico. Be sure to ask for her suggestions if you're unsure what to do around town.
3. Beautiful home - Her spacious and warmly lit flat is very nicely decorated with lots tasteful decorations and vintage furniture. You can tell she put a lot of thought into it. Not to mention her terrace is like a garden and great place to relax and read a book. You can hardly tell you're in a city of 25 million people!
4. Very clean - Anita has her flat professionally cleaned so everything is spotless.
5. Safe - Her building requires a key to enter and exit. It's well lit even at night and on a main street so I felt safe during my visit.
