In a busy July week this place is like children's amusement park. Busy and loud. If you're looking for peace, quiet and relaxation, not easily available here. That being said, the situation is probably very different on a November or January weekday, our visit was during the busiest Finnish vacation month.
Breakfast, busy and crowded. Dinner, you'll have to queue or book a table from the more expensive option. We had a room on the "castle" (not a castle really), an okay room, but some issues with the level of housekeeping and WiFi not great.
Spa is loud, busy and targeted for children. The sauna world (separate fee) was very nice and more quiet.
The beach and the outside grounds of the hotel are nice with pieces of history remaining. A nice cafe on the beach.
Was tempted to rate this as two, but do realize that during a less busy time things might have been better. Also the staff handled our feedback well.
