My siblings and our spouses (6 of us total) rented the house and had an amazing, highly memorable experience. Firstly, the location and neighborhood can't be beat -- it's on the Manasquan River with ocean views, on a very quiet street, walking distance to the beach (15 min walk, 5 min bike) and very good restaurants in the area.
The house is older, but the furniture, bedding, supplies, etc. were high end, very comfortable bedding, and professionally decorated interior. We were one of the first families to rent the house and a lot of stuff was brand new. Most importantly, everything was very clean. Manager was very responsive, gave us good suggestions for local restaurants (we enjoyed dinner at La Mondina).
Highlight for us was waking up to the sunrise over the Manasquan Inlet each morning. The view from this house is the best there is at the shore. Also very cool to watch the inlet boat traffic from the back deck. We plan to stay again in the Summer and Fall.
