I've stayed here a couple of times with my girlfriend and it's a very nice hotel! The appartments are spacious, nicely decorated, with a kitchen and a big enough bathroom, a nice balcony, great living room. Almost like a real appartment! they do show a bit of wear here and there, but it's all clean.
The location is good on the edge of the little town terschelling-west (the main town on the island) and the woods. Great starting point for a walking or bicycle trip.
Swimmingpool is next door. Which is ok.
Breakfast is good, lots of choice, and the overall service was very nice.
We prefer Hotel de Walvisvaarder ourselves because it's a bit more remote and romantic (if you get the bigger rooms there) but all in all Boschrijk is an excellent place!
