Marco and his girlfriend/wife are really nice people with basic conversational English. They were nice to us and easy to live with.
The room in their house is really small with minimal space to move around. However the room and bath room were clean. The bath room has a problem of one of the shower knobs dripping which was an eye sore.
The geyser for hot water was not straightforward and we had to learn through usage how to operate it.
We also once faced a problem of our room door not opening which resulted in us having to sleep on the couch till Marco returned within an hour. He promptly was able to open the door and apologized a lot , which was genuine and nice of him.
We stayed for 5 days and cooked every night. He has a decently sized kitchen with all basic utensils and a stove.
His house is located in the central area with easy walking distance to many iconic CDMX sites. This was the best part about staying at Marco's!
