Zack is extremely responsive. He even next day shipped portable space heaters to us as the weather was cold while we stayed.
The unit was a very clean, no frills basement/ground level unit. Zack provides such nice amenities such as disposable eating utensils/plates, water heater for tea, microwave, mini fridge. Location is fantastic, just minutes walk away from groceries, restaurants, and public transportation. Note that there may be noise coming from the upstairs unit. It didn't bother me but it may bother some people so heads up. Also wifi quality is pretty good. Both of us were able to have video conference calls at the same time.
