Had a pretty comfortable stay for a month at Melissa's place. I'm not a huge pre-war building fan but the location was so awesome it made up for it. It was close to loads of great restaurants, bars, grocery stores, a few blocks from Barclays center and only half a block from the train station (C line). The area was safe even late at night.
The apartment is on top floor, there's a elevator but no doorman (doesn't really need one). It's pretty spacious for a NY apartment with good sized living and bedroom. Super comfortable couch and big tv. Bed was very comfortable too and loads of storage space.
Downsides...
Kitchen was small and ok for basic cooking. Bathroom was very small too.
There's also 'old building' quirks like noisy radiators kicking in a 6am and exposed hot water pipe in the bathroom. I guess it's part of the pre war charm!
Melissa was a fantastic host, super responsive and lovely to deal with. No issues there!
