I have absolutely no complaints and only compliments about our stay. We actually ended up staying at the home more than we anticipated given all of the amenities including the big things and small things. I'm going to try to concentrate on things that are not mentioned in the description.
The private beach is literally just down the road, and it is a great beach -- all sand, no rocks, and no seaweed. It's an easy walk, or there is a parking pass, or you can take one of the 5 bikes. Speaking of getting to places, the same goes for Osterville Village. It's just down the road and again you could walk, take a bike, or park in town. Osterville is very charming and has great restaurants and an ice cream shop.
The home is in a quiet neighborhood, and the yard is spectacular. It's a very relaxing, serene environment. The back yard is much larger than it appears in the pictures. There was plenty of room to play yard games (all provided) both in front of and behind the pool. While there is a privacy fence, it is naturally private with foliage which seamlessly merges with the fence. The pool was great, and it is decent in size and has a shallow end and a deep end. There was plenty of seating and pool toys/accessories. We spent a lot of time around (or in) the pool. There is shade somewhere around the pool when you need it. It was in the mid- to upper-70s outdoors during our stay, and the pool remained at a decent temperature. The outdoor shower is heated, and if you close the blinds in the family room, is private.
The inside of the home is tastefully decorated and is a comfortable and relaxing environment. One of our family members was in a wheelchair, and there was only one room that she could not enter unassisted. I feel that the inside is well-represented by the description and photos, so I won't go into too much detail.
The owner was great to deal with and is a very nice person. She contacted us during our stay to ensure that everything was up to par.
Some random thoughts: get ready for some air hockey as playing on the full-size table quickly becomes addictive even if you've never played, and ask the owner before you bring something that is not listed in the description -- they probably have it.
I hope to stay here again next summer.
