We had a wonderful week in Konstanz and the Jonners' rental property made an ideal base, very well located in an attractive residential district with the lake, local woods and a mini market / bakery all nearby. Buses are very frequent, reliable and fast into Konstanz (inc. for ferry / train connections) and to Mainau. The property is small but perfectly serviceable and pleasant (probably for up to 2 adults and 2 children?), only downside is the small and rather dimly lit kitchen; lovely bathroom and shower though, and wifi, widescreen TV and DVD player are all provided in the main lounge / sleeping area. Landlady very helpful and neighbours friendly. Very reasonably priced too. Happy to recommend.
