I stayed here for one whole month.
I didn't need the AC or heater so I can't speak for those but everything else worked perfectly, (appliances, water, power, wifi, etc.).
The few guests that happened to also share the place while I was there were all friendly and courteous.
The room I stayed in, (Room D), was perfect for me; it has a small coat closet, table, chairs, nightstands, and small lamps. I work remotely so I spent many hours inside the room and had no issues with the wifi.
While it's possible to order food and groceries, there are plenty of stores 5 min away, (delis, bakeries, restaurants, grocery store, barber shop, beauty salon, etc.). There is even a laundromat almost a block away where you can drop off your clothes and pick them up later washed and folded if you like, (if you want to do your own laundry then you need to purchase a card for a $20 minimum, which you then use at each washer and dryer and can also be used to purchase detergent and softener).
The one thing to keep in mind, which can't be helped, is the potential for noisy neighbors. With guests, the noise will likely include banging of doors as they open and close them, or the stomping of feet if they need to use the restroom at night. With actual neighbors, (during my stay), there were two separate parties on two separate weekends that got a bit loud, with one of them staying alive until 4am, (I think it was a quinceañera). I've never been able to get used to wearing earplugs to sleep but I'm already used to sleeping with background noise, (the new iOS feature), so I simply put that on and didn't have an issue, (I only know that one party was still on at 4am because my girlfriend had to get up at that time to use the restroom).
Natalie was very responsive throughout my stay and it's apparent that she has plenty of experience with this setup because things are set up in a way that makes it clear you're sharing the common areas, (cabinets are labeled, even inside the fridge), and there are signs through the apt reminding people of some of the simpler do's and don'ts.
I'll definitely stay here again if I have to visit Queens again.
