Sonder ARIA was a great place for us to stay. Being in Roma sur, we had walkable access to Roma and Condesa. The central part of CDMX was a quick uber ride away. It is located next to the metro but we didn't get the chance to ride it. The place is practically brand new and there is always a security guard at the front desk. Sonder sent TP to us right away when I communicated that we were out. It was great to have a kitchenette in the room. Our bed was a nice king size but a little too firm for our taste. Maybe larger/firmer pillows would help? The only other suggestion would be to add a mirror in the living room or bedroom. It was a little too crowded in the bathroom for two people to get ready at the same time. Overall enjoyed our stay and would recommend to friends/family!
