This place is has it's pros and cons like other reviewers have said, but overall I'm very happy to have stayed here for 2 months.
PROS - Location - great location near David park and restaurants and Reforma. Going out the front door and having so much around definitely made the experience fun! Rooftop patio - this is a huge plus for the area, a good spot to have morning coffee and writing, or to exercise, or to host for drinks with friend. Size - generally the apartment is large and spacious for the area. After visiting other friends places, the size made this place feel luxurious. Character - the historic character is nice, with the high wood beam ceilings and the wood floors. It also felt more like a real home, rather than an overly designed airbnb. Host - Nashe was nice, friendly and responsive. The neighbors were also very friendly.
CONS - Noise - the place is old and is on a fairly busy street, so there is noise. You will hear traffic, all the street sounds, neighbors talking or dogs barking. For the most part this eventually became background noise and you cease to really hear it. Deferred Maintenance - as others have said this place is falling apart a bit. The front windows are held together by tape. The kitchen floor is very uneven. Bits of pieces occasionally fall from the roof. The fabric on the couches have fallen off so big soft blankets are draped over the couches. Kitchen - it is not the best for cooking and the frig is small. I was able to use and cook for 1 person, but it's not the best for cooking, but you don't cook that much with so many great restaurants around. Shower - the water was hot/warm, but always leaked out to the bathroom floor. You always need to put the mat down outside the shower and it gets soaked, it's best to hang dry this mat after every shower. Bed mattress/sheets/pillow - Don't expect high quality, plush sleep furnishings. The pillows are a bit old and flat.
After all this I would definitely recommend this place for a stay.
