Andrea was the best host - she met me the evening I came in and took down our information (which felt very safe / I appreciated her having it in case something came up), showed us around the apartment and got us extra blankets.
The house is gorgeous - and there is a twin bed in addition to the full/queen bed. It was located in a great area - super walkable - and very safe.
She called us a taxi for the aiport when we left, and was very easy to get in contact with. I left my bag in an uber while we were staying with her (it had the house key in it). Andrea met me and let me into the house, gave me a spare key, helped me talk to uber, and was so kind about the situation (I got my bag and the house key back). Next time I am in Mexico City I will try to stay here again - a wonderful airbnb.
