We stayed at this house for 10 days in late July/early August. While it's not on the lake, nor can you really see the lake from the balcony, it is a very easy walk (via right-of-way path) down to the lake. There are boat slips there as well as a small beach and picnic area.
We also used this house as a home base at night. During the day we went tubing on the lake, blueberry picking, go cart racing, swimming, and a day trip to Hershey Park.
The house itself was great. We had eight people and two dogs, but there was plenty of room for everyone to sleep. My only real complaints are that the dishwasher is small and the large refrigerator is in the basement (a small one is in the kitchen). Other than that, it worked out just fine.
