The location is great to get around the area easily via bus, taxi, or metro.
The beds are very comfortable and the decorations are pleasant.
The towels are soft and comfortable as well.
The wifi access was clearly posted near the front door.
There are numerous small kitchens on the block and a lot of places to walk to nearby to eat or shop. 25 minutes on the metro 2.5 blocks away or 30 minutes on the bus a block away will get you to the Bella Artes or Cathedral area and even Reforma.
The location is fantastic, but the apartment itself has room for improvement.
The bedroom walls have two large holes near the ceiling between them so if one bedroom has lights on the other bedroom is illuminated without any easy way to stop the light from bleeding between the bedrooms.
One bedroom has a bathroom, the other bathroom is built under the stairs and is very difficult for an adult to crouch their way to reach the toilet. So if multiple adults are staying it was more comfortable to all share a single bathroom in the back bedroom rather than try to use the bathroom by the kitchen.
The neighbors above pass at all hours day or night and there is only light plyboard forming the upstairs floor of the entry way so whenever people pass up and down the stairs to the apartments above or stand around and talk in business and staircase you can hear everything in the bedrooms. With the bedroom doors closed they rattle in the frame when people pass up and down the stairs. The neighbors left every morning starting at 6 am, loading boxes, and dropping and dragging things above us ... this would continue each morning until about 7:30 or 8am. Then the neighbors would pass in the evenings until around 2am -- on the weekends they would laugh and talk loudly into the night. It definitely isn't a quiet space.
The space also receives no natural light and it is much colder inside than outside on the street. I would recommend bringing warmer clothes than you expect just to pass time in the apartment.
There's a water pump located just outside the bedrooms that runs when the water reserve is low. It ran multiple days during our one week stay often for 1-2 hrs at a time. We asked Mario about it and he sent instructions on how to turn it off, so it was something that he was aware of and would have been nice to know before we were awaken to the loud pump motor at 6am.
The water heater is located on the wall near the pump, it's hard to reach for most people and when we arrived it was adjusted to the maximum setting which caused the failsafe to activate and not produce any hot water. We figured out how to adjust it but the location is inconvenient to reach and adjust because it is over 2 meters up the wall. Having an indicator on the heater as to where to set the dial would be have been helpful.
Only one shower (of the two in the apartment) will receive hot water if both showers are operating with the hot water lines in the showers open.
There is no potable water in the apartment on arrival, but the nearest pharmacy or 7/11 is 1 block away.
