Ricardo's place was really great--definitely my favorite of the places I rented in Mexico City (5 of them over the past few years!). The space is nice and full of natural light, it feels like home, and there's plenty of room. The kitchen isn't great, but I knew that going in. It's a very lovely, well-designed location.
The only downsides are the air flow (it can get hot, but you open the windows) and the bad internet. It cut out constantly, and was only strong in the living room. Other than that, this apartment is super conveniently located, quiet, and very comfy. There are lovely touches to boot!
