I will preface this review by saying that Switzerland is outrageously priced everywhere, so we were looking for the best bang for our buck with the criteria of no more than approx $200AU per night.
All things considered we fared reasonably well with The B&B in Luzern. We booked the attic room which unlike the other rooms, has a private bathroom. We stayed 4 nights. The room was basic, plus a few extra niceties thrown in: spacious room, loft windows, big bed, sofa, TV. Breakfast was a fairly limited buffet, but nice.
It was a comfortable, clean, and pleasant stay. However for our nominated budget we procured more high end accommodation in every other European country on our trip. The B&B felt like backpackers digs with an extra star added. This is in no way a criticism of the hotel. This is an expensive country to visit & for the money I doubt we could have done much better. The staff were wonderful, friendly, & professional.
Finding a decent room that is affordable in Swiss francs is challenging. I would recommend this hotel with the proviso that you should adjust your expectations downwards by 1 star from other European destinations that you may be familiar with, dollar for dollar.
