I stayed one night in a junior suite. Although this is somewhat more costly than a standard room, it's worth it for the wonderful view. The room was very spacious and well equipped with everything you'd expect, except perhaps a mini bar (but drinks available to order from the bar anyway). I slept fantastically well, which is unusual for me in hotels, thanks to comfortable bed and quiet.
Other reviewers have said the breakfast is disappointing, but I didn't find this. Fresh orange juice a particular plus!
Staff very pleasant and speak English (luckily for my poor French!)
Roscoff is a nice town to stay in and this hotel is within walking distance of the sea front and shops/restaurants. Free parking outside in the square.
