This is one of several newly renovated apartments in the building. I believe I was one of Santi's first guests. I didn't meet Santi personally but his right-hand-man Carlos checked me in. Both of them speak great English and were very eager to make sure their guest had a great stay. I actually ended up getting moved into Unit A on the ground floor since they were just getting WiFi installed for the whole building and had not yet made it up to the 4th floor unit (that this listing is for). On the 2nd day of my stay they WiFi was installed for all floors so should be good now. The new internet is a big upgrade too, much faster now! Signal is a good through most of the apartment but gets a little weaker in the bedroom which seems to be the norm for older buildings. Kitchen was basic yet effective: plates, cups, bowls, silverware frying-pan, pot. It's hard to justify cooking anyways when there is SO MUCH good food in the city to try. Hot water supply is good and heats up fairly quickly. Bed was firm and comfortable, pillows were good. I had to ask for an additional blanket after the first night as it got a bit chilly at night. Carlos was quick to deliver after my request! Window shades do a pretty good job of blocking out most ambient light at night. At first I was a bit apprehensive about staying on the ground floor as street noise in CDMX can be pretty bad sometimes, but this apartment is on a pretty quite low-traffic street so there wasn't much noise at all, even on the ground floor. Speaking of location... if you are visiting CDMX as a tourist for a short stay to see all of the sights, this is probably one of the best locations you can find! It's a 30-second walk around the corner to Fuente de Cibeles which is one of main bus stops for you to catch the city tour buses and hop-on hop-off busses. You couldn't be any closer and still be on a quiet street! It's also only a 6 minute (400m) walk to the metro stop of Insurgentes. So really good access to public transportation. The area is also quite safe to walk around, even at night. The only negative I can think of is there's not much natural light and feels a bit dark, but there are plenty of electric lights to light up the place. Perhaps the other units on higher floors have more natural light. I believe they are also going to be adding some big lush plants into the apartments which will be a nice touch! As one of the first guests I can see they are putting a lot of time, money and effort into making this a great AirBnB. I see bright things in the future for them! I can certainly recommend others stay here while visiting one of the great...
