Rivka's was one of a couple places I stayed at after moving to the City while I was still looking for an apartment, and hers was certainly my favorite. Carrying my bags up the stairs was a bit of a chore, but from there the stay was nothing but pleasant. Rivka's very knowledgeable about the area and always had a helpful suggestion for places to check out.
The apartment is blocks away from prime subway spots and the Brooklyn Museum and Brooklyn Public Library are only a couple stops away, if not walking distance if you don't mind a trek.
I loved staying with her and highly recommend it for anyone looking for a comfortable place to stop for either a trip to the city or moving transition.
