I have stayed here a few times while travelling for work. It's conveniently located right next to a subway stop and accessible via the Path system of underground tunnels. Most rooms feature a full kitchen and some even have a washer/dryer. It's extremely convenient if you're travelling for any length of time and the price is decent. I have had great experiences with the customer service. Asking for directions and recommendations for places to eat have always been met with knowledgeable answers.
My only complaint would be the building itself. In one room, the toilet would loudly refill it's lost water every half an hour or so. In another, there was a distinct mildew smell coming from the cupboard where the mini fridge was stored.
All in all, if you aren't spending much time in the actual room, it is a great place to stay.
