We loved staying in the apartment. It is super centrally located, an easy walk to all of Roma/Condessa, the Centro Historico is also walkable (albeit a longer walk). Luis and Salomon were great hosts, providing speedy responses to questions, and meeting us at the apartment super late for our check-in (as we didn't get off the plane and through customs until close to midnight). The hosts were also super kind in letting us leave our luggage in the garage in the interim hours between when we checked out of the apartment and had to head to the airport.
Having a washer/dryer in the apartment was very helpful. We loved the selection of plants in the studio, the apartment receives a ton of natural light, which can be subdued with the shades drawn, but was wonderful to wake up to. The studio is on the second floor off a relatively quiet street, but some mornings I wish I'd brought ear plugs as the streets in CDMX are much livelier than in Seattle (the garbage truck ran by a few mornings we were there and the bells on the truck announcing its arrival pierce right through the windows). Overall we had an amazing visit in CDMX, loved staying in the apartment, and would absolutely love to return and stay again!
