The place is very cute and well located. Just in a couple of blocks, there is cafe Lardo, which is one of my favorites bakeries. Try their envuelto de dulche de leche and roll de guyaba!
The apartment lack ventilation and when it's cold outside you choose either humid or cold. But it's very common in Mexico, so I wouldn't count it as a huge disadvantage. The parking place is in a garage, which is nice and much safer than on the street.
Five stars, very good for short-term stays!
