Maru is a great host. In CDMX alone for a few days, I wanted to stay somewhere where I wouldn't feel isolated or lonely, and Maru's house was perfect--because of the restaurant in the backyard and the various family members and friends who cycle through her house, there were tons of opportunities for conversation and a very communal atmosphere! Maru was very generous and made me feel like a family member. The room is very comfortable and, due to the walled-in garden, there are birds chirping and plants all around, which makes it a very soothing respite from the city.
One note: one of the dogs in the house is very territorial and barks and lunges at you each time you arrive in the house. You can generally avoid the dogs by entering through the back door, and Maru and everyone else does a pretty good job keeping him under control, but if you are at all nervous around dogs, you might want to find another spot. I'd say the pros still outweigh that con, though.
