This is Frau Eva Frei's home and she rents two of the bedrooms as a B&B. Found it on the Swiss B&B website. Pleasant home, scrupulously clean, residential neighborhood surrounded by forrests that apparently have nice hiking trails. We stayed one night in a room with two very comfortable single beds. Lots of towels. No soap or shampoo. Shared bath. Good breakfast of breads, jams, meat/cheese, beverages. Ten minute walk (uphill) from the train station. There is bus service until about 7pm. Cash only.
Spiez is a beautiful little town, on a beautiful lake in a valley one train stop from Interlaken. Lots of good restaraunts, good TI.
We stayed here one night after visiting Muerren so that we could more easily make an early morning train connection to Italy.
