Having read several (mostly negative) reviews I wonder whether these people stayed at the same campsite as we did. European sites are very different from those at home! We stayed at Sanssouci between 3rd and 10th July and enjoyed 8 nights for the cost of 6 after which 'high season' prices came into force. It is a waterside campsite, but with easy access to Potsdam and Berlin. In July it would be unreasonable to expect a tranquil environment anywhere in Europe. We were shown to a very nice pitch overlooking (but not actually on) the lakeside. We did not eat in the restaurant as we were turned away on the Saturday evening at 20.45 even though we were told they would still take orders until 21.00. However it was extremely busy and seemed quite expensive for what was on offer. To our surprise WiFi was free but you had to request a code from reception. When we first arrived it lasted for 24 hours but as the site filled up the duration dropped to 3 hours but you could always go and ask for another one. The facilities were adequately clean and there was plenty of hot water. There was evidence of 'a work in progress' in the toilet block due, I think, to a collapsed ceiling but this did not cause a problem. The free shuttle service was excellent and a phone call to the provided number (after 17.30) brought the mini-bus to the station in a few minutes. I don't know that we will ever visit Potsdam/Berlin area again but if that is what you want to do then this is an ideal campsite to use as a base.
