We had a great late summer stay at Ricardo's little weekend house in the quiet canal district of Klein Venedig. Ricardo was very helpful (picking us up from and dropping us off at the S Bahn station, giving us a tutorial for how to use the motor boat). There's no drinking water on site but the local supermarkets are less than 5 minutes away by bike. The lakes are easily accessed by bike, boat or S Bahn. Berlin is 30 minutes away by S Bahn and Friedichshagen is a nice place to visit right by the Muggelsee. We'd gladly return.
