Ariel's place is super clean, and the location is the best. I went to visit family in CDMX and stayed in Ariel's place for the weekend. It is very well located near the national monument for Revolution. it is near public transportation, there are many good restaurants bars and coffee places within walking distance.
I highly recommend Ariel's place, it is very safe, with a security guard 24/7 and secure underground parking.
The checking process is very easy, Ariel's is an excellent communicator.
