Hotel Østersø is a hotel next to the coast. There is plenty of parking available if you come by car. The hotel is unmanned, which means that you must have a smartphone and you register digitally on a screen at the entrance. Once registered they provide you a code to enter the hotel and your room. There is no front desk, no shops, but a vending machine. The hotel looks like a time capsule where most of the original inventory from the 1970s is still in place. The rooms have the very basic things, but provide no amenities. On the positive side: clean room, black-out curtains, electric sockets, private bath with shower, warm water and soft towels. On the negative side: the smoke detector beeps once per minute for extended periods, and makes it very hard to sleep. Bring ear plugs . Either it is too sensitive or the batteries need to be replaced. The mattress was overly soft, not meant for heavy people.
The place is just 20min from the border to Germany and is suitable for stays on the go, or for urgency, but it does not offer the comfort to provide a good night sleep.
