The apartment is very nicely done and offered everything you need for a good time in NY. The neighborhood is "still up-and-coming" with very sweet and nice places to eat and sit, mixed with the more rustic charm of some industrial complexes and non-gentrified blocks. If you want to go were the heat is, Williamsburgs central area around Betfort Av. is only few subway stations away and the same line brings you with little more stops to central Manhattan.
We had a very good time in Guillermos apartment and recommend it to everyone who looks for good affordable place to explore NY.
