On the south bank of the river, this three-storey hotel has clean, simply designed rooms with stiff mattresses and simple furnishings (plus fridges). It's well worth paying the extra euros for a room with a view (and small balcony) overlooking the lake and historic centre.
There's also a waterfront restaurant (meals €25 to €35) with a big vine-covered courtyard. It's particularly striking in spring, when the wisteria are in bloom.
