I recently stayed at Shun's apartment (Sept 2010).
The apartment is perfectly located in the heart of Manhattan. It is a close walking distance to times square, and major subways that makes commuting around NY very easy.
I was in NY to take dance classes, and Shun's apartment was perfectly located within walkiing distance to Broadway Dance Centre (10-15mins), Steps on Broadway (20 mins) and Ailey Dance Centre (5-10 mins).
Shun was very hospitable allowing me to use his lap top and internet. The room was spacious and entirely adequate as I only came back late at night to sleep for a few hours. The facilities were clean and adequate.
Yes it can be a little noisy at nigh which made sleeping a little difficult, but the room, its location and the hosts were exactly what i needed for this trip.
I would thoroughly recommend this apartment to any single or couple looking to stay somewhere convenient in NY.
