Shun's unit is a simply-furnished room with a bed, bedding, functional shelving and seating, a microwave and small refrigerator. A large window looks out to W 55th Street from the second floor. The picture in the listing represents it well.

Stairs lead to the second-floor unit; Shun helped with my luggage, and was kind and communicative. (There is no elevator.) First entry is by door buzzer; after that one has keys. There is street noise at all times of day and night; one gets accustomed to this and to audible chaos in New York. There is some noise abatement from closing the window and curtain.
In October, it was chilly: a nice touch is the ceramic heater. Cooling is accomplished by raising the window slightly. The (shared) bathroom is just outside the unit door, and also has a permanent-on heater. The hosts ask guests to avoid using the bathroom 7-8mam weekdays, but this can be negotiated.

I saw the hosts only briefly on arrival. The unit is ideally located: near the theatre district, and four blocks south of Columbus Circle, near Lincoln Center. There's a lovely 24-hour cale/deli around the corner on 8th avenue (Bread Box), and a sizable (and busy) Starbucks on 57th two blocks north.

I slept reasonably, given the noise outside. If this, or bedding (hard/soft) or other details are important, these are things to discuss with any host. I'm just learning about the features important to me.

I recommend Shun's unit to anyone who needs simple lodging in the theatre district.
