Great Apartment with beautiful roof terrace. It's located very central in the mexico city central district. You can reach everything by foot and the next metro station is like a 5 to 10 minutes walk away.
It is a safe and clean apartment and Francisco takes care of you with a lot of information and tips on whta to do and where to go. Also you can ask him anything.
The only down side is that it can be noisy sometimes (but thats normal in a place that central in a big city). But there are earplugs provided so thats not a problem at all
I can recommend to stay here.
