    "Lived here for more than 10 years. Everyone is really friendly and family oriented. You have to love yourself and understand that people are not always against you but do want to see you win. "
  • Suevolkman

  • Suevolkman
    "We have the Christmas Electric Light parade, we have Benner’s Farm which is unique and offers classes and camp. We have a diverse community due to the university."
  • Gimars123
    "Great schools and many opportunities to explore the outdoors. Parks, beaches, boating, museums for the kids to utilize. "
  • Daniel F.
    "Neighbors are watching everything that you do and everyone is stuck up. Commute is horrible because of the college students who do not know how to drive a car and everyone is stuck in traffic because of the main roads are few and everyone cuts through the neighborhood. If you like nosey eighties and being stuck in traffic then this is your community"
  • Ginny E.
    "More of a bedroom community. 2 plus hours to major city. (NYC). I am retired so I don’t commute, but traffic heavy all day."
  • Chriscona
    "Great neighborhood. We love it here. Scenic and very cozy and quaint. The residents are very kind and take great care of their homes. I always get the feeling that people are very happy here, and are grateful to live here. People smile and say hello as you walk by. It’s a warm and welcoming neighborhood."
  • Jesse W.
    "Very fast passed and friendly. Lots of stores with a open community vibe. Very safe with police around and never hear anything bad about the town. Not like other places on LI, it’s very safe which is the most important."
  • Peter M.
    "there is a 3 mile walking trail that is great for runs, family walks or bringing your pets. we live close enough to walk to the trail and love it. "
  • Nette523
    "People. Schools. Events. Local restaurants. Cul de sac. Education. The local university as well as 3 local hospitals. The ferry to get up north. Every type of store imaginable as well as every type of doctor."
  • Arnold F.
    "We own our property. Located on historic Strongs Neck in East Setauket this traditional colonial on a cul de sac is a fantastic location to live and raise a family. Excellent Three Village Cental School District. "
  • jac19
    "I live in this area. The neighborhood is very pleasant with large homes on lots about one acre in size. Need a car from shopping but the area has a number of nice walks, including to Port Jeff Village."
  • Gregory B.
    "Great area on the north shore. Minutes to beaches, water activities, close to SUNY StonyBrook, Port Jefferson Village, two train stations, the Cross Island Ferry (to Connecticut) many restaurants, nightclubs, activities, historic village... something for everyone."
  • Nawrocky
    "Great area. 2 mi to three supermarkets, 15 min to Smith Haven Mall, 10 min walk to West Meadow beach, 10 min to Stony Brook University."
  • Sohagirl
    "People move here for the historical reputation of good public schools, but that is not the current situation - the schools are rapidly declining in quality. Home break-ins and other crime is on the increase. Too far to comfortably commute to the city. Lots of university students in this neighborhood means it tends to be loud on weekends and Gnarled Hollow is like a racetrack."
