The facility itself, the location, and the friendliness of the landlords were fine. However, we were surprised by an unexpected fee for the so-called additional costs (Nebenkosten). The advertisement mentioned a climate tax and a deposit, there was no information about other costs. However, after the end of the stay, the owner charged the costs in the amount of EUR 20 per person, which for a group of 7 people resulted in the amount of EUR 140 + the tourist tax for 7 people, EUR 210, the amount of EUR 350.
