I had a great six-week stay at Kaz's attic space, a good sized room with bed, desk and chair, shelving and closet space, plus a nice bathroom. It comes with shared kitchen privileges on the downstairs floor that has three guest rooms, and living room.
I stayed there in Spring and had no need for using the A/C, but during summer, the portable air-conditioner can be moved around.
What I loved most: a private bathroom, kind hosts that responded to questions quickly, and location. Two Metro stations are five blocks from the house in opposite directions, and the 7 train gets you to Grand Central Station in Manhattan very quickly, and most of the ride is above ground, so nice views. Sunnyside has so many restaurant choices and cuisines from around the world. Also, Sunnyside is a laid-back neighborhood where people are patient, friendly, and kind.
