I enjoyed my stay at this casita! It's fit with all kinds of trinkets and Mexican cultural decorations. I booked last minute and Diana was immediately very communicative, responsive and professional. It was a nice welcome to have bottles of water and fruit waiting for me. Safety was my biggest concern and with multiple locks on the house doors as well as a lock on the door to enter the complex, I felt fine. The neighborhood was also very comfortable and it was a nice bonus having Starbucks across the street as a secondary place to work and use wifi. Things that could be improved are the addition of an iron and making the bed a bit more comfortable, however I did sleep peacefully because the area is so quiet. Diana was also kind enough to send me recommendations for vegetarian restaurants in the city. Supermarket and really good restaurant are within a 5 minute walk. Don't worry about there being no heat or AC. Mexico City is mild enough during the day and the night to be comfortable. Opening and closing the windows was enough for me but the casita has a fan and extra blanket if you need. Wifi signal is also strong. Thanks, Diana!
