overall a good apartment and excellent location.
the location is literally a stone's throw from the main Historic centre with all the tourist attractions and walking distance to the majority.
the accommodation is as shown on the site with a door person downstairs 24/7. I was on the 2nd floor of the block if apartments and there is a lift and a central atrium, so all the floors to the apartment are open to this central atrium.
the apartment was well furnished, comply bed, clean with a living room area and small kitchenette and TV. Bathroom clean and spacious shower with good pressure and hot water.
I was there for 6 nights. the main issue for me was the level of internal noise! not traffic but noise from other occupants in the apartment block. on the first night there were children running around upstairs on the corridor and because of the atrium being open I could hear there screams until 10:30pm when possibly the parents got them inside their apartment! Also day 2&3, somebody was playing loud music on one of the floors until about 11:30pm. I could hear the TV from the room next door and I could hear the person walking around in the room above me!
apart from that the apartment is a good place to stay to visit Mexico city but if you like me are not tolerant to noisy neibours, this apartment may not be the best choice! I don't know if more of the apartments are Airbnb or actual residents.
