This is a perfect little place for two in Mexico City. It's super clean and the bed is really comfy. The place is equipped with everything you would need (towels, shampoo, conditioner, soap) and I was very pleased with the kitchen because it has a good amount of cooking equipment and also a bunch of spices and other things that perhaps previous guests left over? We didn't get to meet Karla, but her dad did the check-in and communication with her was never a problem.
The only thing I would say is that the location is not super close to all the sightseeing stuff. It's about a 20 min walk to the nearest metro station, but pretty close (7 mins) to the metro bus station. It's really not a bad location, but just expect around 40 mins to get to wherever it is you're trying to go!
