It's a really nice place to stay in if you're on vacation in CDMX. The metro is close, it's not far from to centro and neighbourhoods like roma. The room was sparkling clean, the security guards are really nice and caring, Arturo was very fast in responding, communication was great. I saw some people complained about noise in the building but I'm a very light sleeper and didn't notice anything.
If you're looking to use the gym for a walk the treadmill is just fine, not suitable for running though (the band is jolting which makes running impossible). The gym isn't a "real" gym, just a few half broken machines, and shouldn't be advertised as such. Ended up going to a gym a couple of streets down. That's the only downside! Rest was great and I recommend it for a stay :)
