I stayed 2 nights at Shun's place and I definitely recommend him to others. If you are a busy traveler, who will be most likely spending time outside (especially downtown Manhattan) and wants to have privacy and spend quite time for good rest at the end of the day at the place you stay, his place will be the perfect choice for you. The stuffs I listed under [What I did not like] should be considered as minor issues. My overall experience was very positive.

[What I liked]
(1) Location was truly AMAZING. You cannot ask for more. Very close to Columbus Circle subway station and there were many little places to grab something to eat. There are 24 hours McDonald, Starbucks, 24 hours grocery store, Central Park, Shopping Mall and so on very close by. (2) Shun was a wonderful host. He is very flexible, kind, and communicative. He adjusted check-in, check-out time for me and even took care of my luggage on the day I was supposed to check out because I had to wait until 6PM to get in to the next accommodation arrangement. (3) Wireless Internet works very well, and TV in the room has many channels you can enjoy while you are in your room, (4) Fridge, microwave, some plates, and flatware in the room come extremely handy when you want to keep some drinks cold and have little snack without having to use the kitchen

[What I did not like]
(1) It was very tricky to use shower temperature control. The water becomes easily too cold or hot. (2) Lighting in the room was bit dark to me (3) No mirror in the room (4) Heating system was broken at the time I stayed, so I had to use Shun's small portable heater that was not strong enough
