I had a friend coming into town so reserved Mariana's place for him to stay...
Mariana's place was very cute and comfortable, the building staff were very helpful and nice, the location is great -- near public transit, supermarket, Oxxo, etc. -- and communication was great. Mariana gave really helpful details/directions and was quick to respond whenever we had a question.
If any other friends come to CDMX to visit, I'd definitely book Mariana's place again :)
