Chiming in as I was there last week: the buffet is expansive and diverse but I would not say particularly high quality. Quesadilla station was novel but not very tasty, bagels inedible, meats underwhelming, cold cuts cheeses and breads lacked flavor - the fruit was decent. Service was highly variable across our days - high-touch one day to non-existent the next.

Also booked into a Andaz Suite at booking with an SUA; no further upgrade as the property was 100% sold out. I found the layout very disappointing - basically a regular room with another long, narrow "space" at the end of the hall connected with an internal door; that space oddly had its own hall-facing door. The master shower struggled to drain, and was leaking into the master toilet space; I let the FD know but no action taken; we just used the bathroom on the other side of the suite to avoid damage.

One other thing to note (and this may not be unique to this location) is that Ave Insurgentes Sur gets quite jammed what seemed like every day but Sunday. Consequently, Uber pick up estimates should not be relied on so if you have dinner reservations at somewhere unfriendly towards lateness (e.g. Pujol) or timed entry tickets to a museum (e.g. Frida Kahlo), try to leave some buffer -- don't ask me how I know :P

I think this is a property you really choose for the location - the breakfast has a lot of choice but didn't blow me away. Staff were very friendly. Other than that, the only real highlight was the pool next to Cubaya is pretty good with views of the city.

But I would counsel folks to keep expectations in check here.
