Molly's place is a great place to stay if traveling by yourself to New York. Her apartment is a little tight but was incredibly clean. Her kitchen was well stocked with the basics one would need to make coffee and tea, and she has all the contraptions you'd expect in a kitchen. It was super easy to come and go since your door has a electric deadbolt.
The island has everything you'll need; restaurants, a grocery store, bars, live music. I enjoyed walking the main Street every night I was here. Plenty of street parking available just around the corner.
One issue I had was with Molly's internet. if you have unlimited data, you'll be fine. If you depend on wifi, it only seemed to connect in the bathroom. Last thing, if you're 6" or taller you'll have to lean over slightly in the shower.
Here are some things you can expect that no one can change. You are on an island away from the noise of the big city, however you are still in a city just smaller. There are neighbors, cars, trucks, planes. If you're looking for peace and quiet try Jersey. One more thing, if you are trying to keep to a schedule while staying on City Island remember that there's a drawbridge that seems to take forever. it's just one of those things most people never have to consider.
If you're traveling alone, have unlimited data, and are under 6" tall Molly's place is perfect.
