I had a great experience staying at Christina's. A lovely, super clean place with lots of space, and it was great to not have to share a bathroom.
Cleanliness: Just like all the other reviews say, all the spaces were super clean - kitchen, bathroom, bedroom, sheets, etc.
Location: I don't know my NYC geography or the public transit system that well, so when I saw that it said it was only a little over an hour to midtown (Manhattan) where I was working I thought it would be fine. But, coming back from the city it always took me at least 90 minutes to get back (except one time). The track maintenance, late and slow trains, police investigations, etc. all made it a very painful experience to get all the way out there at the end of the 7 line and then having to catch a bus. So, it's not that convenient actually for those commuting to that part of the city, but everyone here seems to do it anyway.
Noise: If you're a light sleeper then I might suggest not booking this place as there was always a lot of noise above with kids running around. I can sleep through almost anything, so it didn't bother me.
Neighborhood: Cute, friendly, and clean. There are great restaurants around and Christina provided some recommendations!
