I use my big, old caravan rarely, so now its possible to book it. If you choose to stay over, you of cause have access to the house with bath, toilets, washing machine, kitchen etc.
Its possible to sleep up till 5 persons, but best for two.
220 volt and lots of lamps.
Heating up by gas, and it works fine in wintertime, but expect a chilly floor.
Bikes is possible to borrow as well. Best way to discover Cph.
