Diana's Airbnb is great if you are looking for a safe well lit place (right across a 7 Eleven store) in the Centro of CDMX. The space is just as depicted in the pictures and Diana was great at communicating with my friend and I. Check-in was convenient and easy (all information is sent via WhatsApp and the key is left in a key lock box). My friend and I (both females) felt very safe and comfortable in the Airbnb, it was conveniently located in the center of CDMX so moving to other parts of CDMX like, Polanco, Roma, Condesa, etc. was a breeze.
The only two "cons" I would point out about our Airbnb are: 1) It was located at the very top of the building so we had to climb a good amount of flights of stairs as there are no elevators. This made moving our our luggage a bit difficult. However, luckily we only had to worry about that heavy lifting twice, once when we got there and once when we left. Additionally, the rooms got very hot throughout the night, making it a bit difficult to sleep (we stayed in April). Other than these two things, however, I highly recommend Diana's place especially if you are female travelers(:
