No housekeeping
Please reader, be warned.
I perfectly understand every traveller has his own experience and needs. I also understand why this "hotel" can be convenient for family and some kinds of travellers, due to low rate for NYC (although it depends, I've seen rates around 300$ not in major holidays) and being closed to Times Square.
So, this review is about my needs and experience (well, every review should be about this).
My rate was fair and this "hotel" (I keep writing "hotel" because in my opinion Candlewood suites lacks of a main hotel amenity) is close to main attractions, Penn station and subway.
A small lobby, more similar to a motel lobby than a major city hotel, an averagely appointed room with a kitchenette.
My main concern is about housekeeping.
I generally divide my vacations in two categories.
On the road/outdoor vacations. When involved in these, I'm quite accomodating. I just need a place to sleep, often for a single night, so a motel will perfectly work and a small kitchenette is a nice plus. 
But when visiting cities, I like to be pampered, at least a little, and eat out.
Having my trash bin overflowing for three days or having to clean my own kitchen is not my idea of being pampered.
So, resuming, your bed will not be done, your towels will not be changed (well, you can bring them at the lobby and change them), your room will not be cleaned, your trash will be left where it is. Housekeeping is provided only once a week.
Let's say you know that and you're fine with that, you like to cook in your room and save some money this way and have no problem to clean up your mess.
Great, you've probably find your perfect hotel.
It's quite different if you didn't know that.
I didn't have any idea about the fact housekeeping was not provided, so it was a really bad surprise to me.
When at home, before writing my review I took care to check again hotel webpage.
Well, in the home page there's a large hotel description, but they didn't care about writing housekeeping is not provided. In the same page, they talk about "suites" feature, not a word about housekeeping.
In the "room" page, there's a long list of feature and amenities, but the no housekeeping thing is not listed.
Try to book a room, and nowhere you'll know no housekeeping will be provided.
You can find it only in the "amenities" page, a page not always readed.
So, my 2 stars is mainly because if you don't provide a main hotel feature, in my opinion you're at least due to state it very clearly
