Sebastian and Adrian's apartment is a great choice for 1-2 travelers who would like to stay in Polanco. The apartment is on the fourth floor (counting the entrance level of the building as the first floor) of an attractive building on a quiet street that is just a block from Ave. Presidente Masaryk, a major thoroughfare that features nice (if expensive) restaurants as well as boutique shops. (The building has no elevator so this apartment would not be a good choice for anyone who has difficulty climbing stairs.) The apartment itself is cozy and the king-size bed is very comfortable. The kitchen is functional but small and probably not suited to travelers who plan to do a lot of cooking. The wifi was strong and reliable with just a few brief interruptions (as is common in Mexico City). The building and the apartment are remarkably quiet so if you're sensitive to noise this would be a great place to stay. The shower reliably had at least 10 minutes of hot water and there is a water filter in the kitchen, which is a great convenience. The building does not have a doorman but this need not be a cause for concern since the neighborhood is incredibly safe. Adrian is a superb host, always quick to offer advice and assistance. In sum, you cannot go wrong booking this lovely apartment.
