I rented Jen's place with a friend for 10 weeks while my friend and I were doing internships in the city. The place is a bit small, but the large windows that let in a lot of light really brighten up the place and makes it feel more spacious. I slept in the loft area and it was plenty comfortable other than the fact that on exceptionally hot days the A/C didn't quite reach up there, and that made for a few uncomfortable nights.
As a host, Jen was fantastic. She was very responsive to any questions or concerns I had, and genuinely wanted to make our stay go well. I would recommend Jen's place to a single person or couple wanting to rent a comfortable space that is in a convenient and central location in Manhattan.
