Alexandra's place is perfect. Clean, bright and modern. All the amenities you would expect are there, including air-con in every room (it was 33 Celsius when we stayed!). Communication with Alexandra was great, she was always available to answer any questions.
If you're wanting to stay outside of the hustle and bustle of Manhattan, but still close enough to reach, then the location is incredible. Within a block of the apartment is a station on the 7 line, which runs 24/7 and reaches Manhattan in about 15 mins, with stops at Grand Central, 5th Ave and Times Square - from those three you can change to a train on pretty much every other line.
You're also a block away from Queen's Boulevard, which has everything from local shops, diners, fast food, nice restaurants and bars. I'd particularly recommend Pete's Diner for breakfast, and Maggie May's bar for drinks.
I'd stay again in a heartbeat.
