Luxury rental apartments and town homes are not very common in Kitsap County. It sounds to me like you should be looking at Bainbridge Island, probabaly in a condo complex that has some units for rent. Another possibility might be Poulsbo Place, which has small single family homes, duplexes and a few triplexes. I wouldn't call them luxury, but they are new and nicely finished. Poulsbo Place is on a bus route and not far from the ferry to Seattle. You might also want to look into the condo buildings on the waterfront in Bremerton. They have some rentals available I believe.
Public transportation is not nearly as developed here as NYC. You have to be very conscious of where the limited number of bus lines are when selecting a location if that is how you will be getting around. Have a look at http://www.kitsaptransit.org/
for bus routes. If you are here because of work, you will need to see if public transportation can even get you there.

Good luck. Kitsap County is a lovely area and close to Seattle.But it is much more like rural upstate New York than the city and the surrounding suburbs.
