The apt is half of the home - the owner resides in the other half. Dominick was very quick with communications and getting things done when requested. He had good suggestions for getting to know the area since we were staying there for a month.
The apt exceeded my expectations. It had just been repainted so was very clean and light. It had pretty much anything we could have asked for.
There were only two of us with frequent guests, and occasional overnight guests. The place has plenty of space including 2 full baths which is very nice. The 4th bedroom, as mentioned in another review, requires pass through the master bedroom so would be best for children related to the "masters".
The beach access is just across a very quiet street - a nice mat walkway takes you up the dunes and down to the open ocean. You can hear the waves from the ocean from the unit. You can watch the boats come and go in/out of the mouth of the Merrimack River to the open ocean from the top deck which is ample. The deck is accessed via a slider in the master bedroom. Plenty of parking is offered (4 spaces) which is critical in a place like Plum Island where parking is at a premium.
The only downside is that the owner's dog tends to greet other dogs walking (via his barking). Most days the dog went with his owner to work or wherever, so was gone a good part of the time. And if you are fond of dogs, you will meet a very beautiful one there.
All in all, I would recommend this property.
