Gosia's place was beyond ideal for my parents' first visit to NYC. It's nestled away on a lovely, tree-lined block just a half block away from Prospect Park. The flat is beautifully decorated and Gosia was a breeze to communicate with. The only other thing I'd mention is that there was a family staying on the floor above and the little ones were up incredibly early moving up and down the stairs (which are above the bed) so something to be mindful of if you're a light sleeper.
