Firstly this is a fantastic location. Really close to a huge number of restaurants. In the heart of Condesa with all its charm. Close to parks and walking paths. About the only thing about the location is that it is not near the Metro. But there is a bus that comes by every 10 minutes or so that will take you to the metro. It is also very close to bike rental stands.
Martha is a wonderful hostess. Could not be better or friendlier.
About the accomodation. It is important to note that this is only about the unit on the top floor. Martha also rents out a room on the floor below, and I have no comments about this. The top floor unit is self contained with a big bedroom/ living room with a comfortable double bed, a couch and chair. It has a kitchen with a dining room table , sink , fridge and stove ( that may or may not have worked) Also a bathroom with shower that always had hot water , toilet and sink. The bedroom /living room has windows that look out on the street and give decent light and air. Being on the top floor it can get warm in the room, especially in April and May, but there was a fan which helped. In the cold of winter there is a heater ( again which may or may not have worked).
There are lots of outlets for charging your devices , and best of all the outlets are 3 pronged ( great for USA plugs.
The kitchen seemed to have basic items, but with so many nice restaurants close by I didnt try it out
There is a washing machine on the roof, which is a really nice feature
It is very secure with good locks to the outside and to the unit.
One downside for some people is the spiral staircase . It is steep and a lot of caution needs to be taken. So if you have mobility issues beware. Another downside is the wi-fi seemed to be cut in and out a lot. The wifi was a little frustrating, but fortunately I had pretty good cell phone data. It is an old building and there is a chance some of the things may not be working in the unit : If there is something you really need ( eg heater or stove) check with Martha first to make sure all you need is working.
I stayed for 17 days and was very glad I did. The location was just so great. There were some limitations but I think most people would really like staying here for the location.
