Amazing.
Check in is extremely easy. Check out is accommodating. The place is fantastic from the simple thing that the drain actually drains, to the availability of a coffee maker, gas stove/oven, dishwasher, and washer/dryer.
We did not even know they were there, but they were available if we needed. We got no complaints even though I felt that some of the others may have been a little loud at times.
They even let us keep our bags after check-in as our flights got delayed.
Wonderful place and I would definitely recommend staying here, the J and L (I think) subway trains are within a close walking distance.
