Olivia's place was really nice - the location is ideal, especially considering it's on a relatively quiet street for Roma and yet is centrally located. Compared to other apartments, the amenities were very good. This makes an ideal place for a group of friends coming to visit the city. For the price, this is very good value - highly recommended!
One thing I missed in our conversations: the address in Airbnb is not the actual house dress - it's a few blocks away. Be sure to get the exact address confirmed before arriving.
The only small thing that could be improved in my opinion: check-in was a bit inflexible (and despite the length here, it was really small). This is not always a problem, but our group was in a different town and didn't know well in advance when we would be arriving back to the city (particularly given CDMX's traffic). We were asked many days in advance for our arrival time, and it felt like we were expected to stick to that estimate despite the variables discussed above. It would be ideal as a guest to have some flexibility on arrival times without causing any issues.
Again, I still would definitely recommend this apartment!
