I stayed here for a month. This is a great place at a really good price. Colima is one of the best streets in Roma! A few highlights:
Really quiet at night (can be rare for Mexico City). It is on the floor above the parking garage, no one uses at night. Upstairs neighbors are quiet and there is a large office building next door that is not in use, at least at night. It is also across from a school, which is really quiet and calm compared to restaurants/ apartments
Great showers (also rare!)
Ruben sets up weekly cleaning service
One tip: as it’s on the second level, it is below the trees, so the apartment doesn’t get much sun and can be cold in the morning. Ruben has a space heater but you may want warm clothes too.
Ruben is super helpful with any requests as well!
