The best low-cost hotel I've found in NYC
I read about The Jane a couple of years ago and put it on my list of places to try. I stay in all sorts of places and don't mind spending money when I get the utility (I flew BA Club Class this trip to NYC) but I don't like spending money on a large room in NYC that I'll just sleep in.
The Jane is nearly perfect in this regard. It was cheap for NYC (I paid $100 a night) which compares to The Pod Hotel I've stayed in before and even run-down flea pits like The Larchmont. Bearing in mind the new Yotel here is about $300 a night and The Jane is a bargain.
But you get what you pay for. The single room is tiny as everyone on here notes so I wasn't surprised. But there was enough storage space above and below the bed to keep my stuff out of the way. I couldn't work out what was original and what was new in the room. They've been very well renovated down to the fake faded carpet that looks old but cannot be. The free wifi throughout the hotel was strong and fast. The staff are great. The bar, lounge and cafe are like stepping back into another era. In a good way. 
Negatives: arriving at 12.30am I needed my sleep and the two girls in the next room came back at 2am and were laughing and talking until 4am. The soundproofing isn't great. Next time, I'd call reception. Ignorant cows. The bar prices are surprisingly high for a hotel that charges $100 a night. $14 for a mojito is higher end bar prices. The prices fit the bar ambiance not the hotel's positioning. I would have preferred a small wash basin in the room (you get one in The Pod 
Hotel) and the room got quite hot at night and the fan is too noisy to have on when trying to sleep. 
I don't mind shared bathrooms (they were always clean and curiously empty when I needed to use them) and you're provided with slippers and a robe for the thrilling journey down the corridor. The rest of the guests seemed to be youngish and fashionable rather than entry-level bargain seekers. 
So I would return here very happily but wouldn't necessarily recommend it to everyone.
