We really enjoyed our three week stay. The apartment is just as described and very well located. The F and D trains are just a short walk, and bus access is also very close.
Although the futon beds are a little hard, the inflatable double bed is comfortable.
Jennifer was a charming host and King, the building super, was friendly and helpful. We enjoyed the company of Smeagol and Stinker (Jennifer's lovely cats) for a few days - making our stay feel very homely.
