We had a great experience at Sidney's place, and would definitely recommend it to other guests. Sidney was really friendly and welcoming, and flexible about check-in/check-out times. The place is very clean and the location is fantastic - lots of restaurants and delis nearby, and super close to the subway so it's easy to get to Manhattan. The only downside was that our mattress was kind of lopsided and uncomfortable.
It's also worth noting that Sidney has a dog - she's a total sweetheart, but does bark when people come and go. That wasn't a downside for us, but if you have allergies/don't like dogs it's worth being aware of.
