First, it's important to share: Raul is a wonderful host and was very accommodating and responsive. His place is spotless and has a beautiful view of the city.
The only limitation and negative things about the place are the *location* and surrounding environment - it's central and can be described as the "Times Square" of Mexico City. There's a ton of noise, and it can be somewhat unsafe at night if you're not careful about your pockets, wallet, or personal belongings, and it can be hectic. It was hard to sleep at night for a while because of the noise and echo from afar that was also deafening.
It's ok for short-term stays or if you don't mind the bustling energy. It was overwhelming for me, as I stayed for 1 month and worked remotely and it wasn't the best spot for my work arrangement and attempt at getting rest. Of course, if I stayed again for anything shorter than a month, this would be top of my short list.
