I've stayed here three times now. The room with the Double bed was large enough for 4 people, along with a kitchen area, full fridge, cooking utensils, pots and pans, sink, microwave, etc. The courtyard is cute, with tables to sit at, free coffee 24/7, and the people at the desk are always super nice. They don't seem to have an ice machine, causing you to have to ask for ice, which isn't that big of a deal, but a bit inconvenient.
The private beach is nice, but the water area is between two large docks, so a smaller swimming area. There are many loungers with umbrellas on the beach with a picnic table and even a grill.
The best thing about this place to me is that they are far less expensive than most every other place on the island, BY FAR. Maybe because they are in Vineyard haven, which is a tiny town and most people want to stay at Oak Bluffs, especially as there's night life there, and much more shopping and restaurants. There is a gas station very close, as well as some shopping and even a supermarket. There's a breakfast place across the street.
I'd easily recommend this motel and stay there again.
