We loved this house. Most of the instructions are in German so just ask if you are unsure.
Don't worry about no WiFi, we had 4g signal. You can see the beach from the house and the conservatory gets lovely and warm so you can dry the towels even of it's raining.
There is a centrifuge for drying swim stuff - perfect! There is a small dishwasher and the washing machine is also small only 3kg but still great to have. All the pots and pans are in good condition. Cooker very clean. Plenty of seating.
The sauna is small but you can fit 2 people easily.
It has everything you need and if you need anything at all they a they are a few doors down.
Would definitely recommend and stay again
