Obviously, it's a fantastic location, right between the two parks. Subway is just a block away. The neighborhood is safe enough and also the building (it has a doorman) and I didn't worry leaving my laptop there.
Sasha and Vicky are really nice and helpful (getting around, recommendations etc). Also, thei're very interesting people who are fun to talk to. They keep the apartment very tidy and clean.
Their dog Jax is well trained and super friendly (and funny).
I definitely recommend staying there.
