Great spacious apartment and an excellent location. The apartment is at 1 minute walk from the subway (40th Street) for the 7 train to Manhattan (15 minutes ride). Sunnyside is a decent part of Queens. You can safely walk down the streets after dark. There are numerous places where you can eat or shop for groceries just around the corner.
The apartment has 2 big bedrooms, a massive living room and a nice kitchen. Beds are good, flooring is like new. It's a bit noisy but that's part of NYC.
Contact with Zain was great. Everything we want (extra set of keys, storing our luggage after check out) was granted within minutes.
