This is a great place to stay in Mexico City. It is very close to all the nice stuff that Roma and Condesa have to offer (15min walk to Parque Mexico, for example) and there are a few nice places to grab a bite around the apartment.
We stayed here for two weeks working from home, and the internet was perfect.
The bedrooms face a busy street, so it could be a bit noisy at night. Nothing that some earplugs wouldn't fix though.
