Anya and her co-host Marcela are super friendly, always there to help. There's a regular building maintenance and cleaning staff who wander about the building, so if anything should go wrong there's plenty of help.
We had a super comfortable stay at Anya's, the room was spacious, clean, plenty of storage space, and a sufficient little desk and chair for work. We got towels and soaps upon arrival. The bed is the biggest bed we stayed in Mexico, and very comfortable. Everything is very clean, there's a cleaning lady coming about every 2-3 days. There's separate bins for recycling and organic, they're environmentally conscious. We had nice chats with Marcela the co-host, we got lots of help on how to use some things in the kitchen, and good recommendations for where to have pizza.
The flat is between Juarez and Roma, so the best location ever if you want to walk lots in some of the nicest neighborhoods. We had lots of fun in Mexico city and we enjoyed our stay at Anya's.
