Alexa, the owner of Don Jacinto's place is a very warn and caring person. She takes great pride in the lovely B& B that she has created, and rightly so. You get great value for the price. The rooms are big and have interesting architectural features including brick ceilings, hardwood floors (your feet won't get cold) and industrial fixtures in the bathroom. I especially liked the counter space and the walk-in shower in the bathroom. And as others have mentioned, the bed and bedding is luxurious.
So that's the bed part of the B&B, next comes the breakfast part, and it was amazing! Every morning there is a buffet spread of really delicious Mexican food. There were also pitchers full of incredibly sweet natural tangerine juice-so good!
Finally, for first timers to Mex. City, Don Jacinto's Place is in Condesa, which in my opinion, is the best location to stay in because of restaurants and sites.
