Decent enough hotel
I stayed two night in the Doubletree Financial Centre. Hotel itself was decent enough, although rooms were very small but you expect that in New York. The hotel is out of the way unless you are doing business in the financial area, but again I knew that before I booked it. But all in all it was fine. Rooms were clean, staff were friendly, strange lobby system on the first floor, so you walk in from the street and are greeted by elevators!! That was probably the biggest bugbear, having to wait an age for an elevator, not enough for the amount of rooms. And it was pretty expensive considering. 
Surrounding area is pleasant. Subway two minutes walk, 7-11 on the corner with a deli. Pharmacy across the road. And a great Irish pub next door that is well worth a visit.
