My family of 5 stayed in Jazz's apartment for 3 nights. Overall, the stay was pleasant
Pros: rooms were spacious; TV with cable; good internet;Jazz had taken care of little things like extra towels, toiletries, coffee etc. He also allowed us early check-in and he process was smooth. Location of the apartment is about 8 min walk to the L train
Cons: while overall the apartment was clean, the utensils, coffee machines, refrigerator etc. could be cleaner. The biggest issue though was that the fan in the living room was tooo slow (and no AC in living room) and this created problem for the person sleeping on the sofa bed in the peak of summer. The queen beds in the rooms are also small-ish.
Overall, we used the apartment just for crashing and didn't mind minor inconveniences.
