Mario is as wonderful as it gets. He carried my 30lb bag up the stairs. Thats why my review isnt 5 stars all the way--it has 4 flights and i dont remember that in the description. So be prepared if you have heavy luggage to lug it up the stairs and across the roof to the other side! Wifi is great! Temperature is great! Water pressure could be better. FYI, limit paper use in toilets--Ive found many CDMX toilets to have very limited capacity as compared to American toilets. This is one of them. But the views are lovely and space doable for one. Two might be a squeeze. What i wish i could give 10 stars is for Mario being considerate enough to provide drinking water upon arrival and then return with a city map for ease of getting around. That's hospitality to me!
