About this House
Lovely setting with perennials on 1.35 acres looking out to the woods and a stream, very private yet so close to Ithaca. You can walk to the bus to Cornell or ride your bike, less than 2 miles to the Vet school. Beautiful open floor plan, full of light with 4 Bedroom, 4 and 1/2 baths, and a room to be finished in the lower level (already ducted for heat) for possible 5th bedroom or family room. New cherry floors and many other updates; which includes a great slate patio and walkway, new gutters and plumbing upgrades. Lovely setting and bird watching from your kitchen window!

9/10GreatSchools RatingParent Rating AverageWe had a great extra Caroline. Maybe kids attended from K-5th. Small class sizes (my sons K class had only 12 kids!) mean lots of teacher-student interaction. Teachers engage the kids with interesting projects and they use the outdoor nature campus for many learning opportunities. The principal was great too. All around a fantastic school!Parent Review4y ago - Beverly J Martin Elementary School

3/10GreatSchools RatingParent Rating AverageIn comparison to other elementary schools of the ICSD, BJM is a truer reflection of inclusion and cultural diversity. If you want your child to learn how to appreciate difference in gender, race, socioeconomic status, ability, and be exposed to a myriad of ways of thought, I would encourage you to consider this school.Other Review8y ago - Enfield School

3/10GreatSchools RatingParent Rating AverageEnfield is an awesome school. The class sizes are small, teachers are enthusiastic and supported by their administrators and there is a real sense of community. There is a curriculum centered around gardens and farming. There’s a creek and sledding hills and kids spend a lot of time outside year round.Parent Review3y ago - Fall Creek Elementary School

9/10GreatSchools RatingParent Rating AverageSouth Hill has provided a great educational and social experience for my kid in the two years we've been there. Classes are small, teachers are committed, there is a great number of aides supporting teachers, and there is good social-emotional support. We have experience some minor level of bullying that has been addressed strongly and assertively by leadership, including direct involvement of the Principal who is very approachable and involved in all school matters. Infrastructure is great, there are plenty opportunities for parent involvement as well, and the school is generally well run.Parent Review1y ago - Cayuga Heights Elementary

9/10GreatSchools RatingParent Rating AverageThe teacher should stop telling the students that they don’t need to go to college. The students should make that decision at the right time in high school. The teacher should focus more on the learning.Parent Review11mo ago
