This is a pretty large place! There's plenty of space for a group of people (we were three, I think the space is ideal for 4, but you can definitely push it way above this if you need to).
Check-in was really easy. The place was clean. It had most common utensils needed for basic cooking (we didn't cook much). The highlight for me was the very well renovated bathroom, with a very large shower.
I did a bit of remote work and the wifi connection dropped on me a couple of times. If you need super reliable internet for *work*, you may pass, but definitely great for normal day-to-day stuff.
The location is actually pretty good if you intend to visit Flushing. There is also a bus line that goes to Williamsburg literally across the street. The neighborhood itself is fun, just not where a foodie would be exited to hang out. To get to Mahattan, that's the 7 line, which would be a 20min ride in normal conditions. Right now, this line will not go to Manhattan during the weekend due to maintenance work, so the trip to Manhattan requires a transfer (not a big deal, just less fun with luggage).
Overall excellent place to stay, great value especially as a base to visit manhattan + brooklyn + flushing areas.
