"We stayed 4 nights at the Monopol. We found it clean and the rooms spacious with very comfortable beds. The rooftop bar is really beautiful as it gives you a view of the town and the lake. I wished breakfast was served there but unfortunately it is actually served in the restaurant on the lower level where there is no view at all. Breakfast was actually a bit underwhelming, especially the sweet options. Few plain croissants, some plain cakes (the same every day), few sad mini donuts that looked like they came out of a plastic box bought at the local supermarket. You can do better here, Monopol.
Car park is available, which is a plus, although it comes at an extra 30CHF per day. I do not think it is a problem but just to be aware when booking. Monopol also has a room where you can store your bikes. I believe it is meant for storing skies in winter and it has not facilities like charging points or pumping station but nonetheless it was useful for storing securely our bikes during our stay
There is a spa on the top floor, which potentially is very nice as you can enjoy a great view of the lake. However, a couple of things put us off from using it more: there are just 8 lounge beds but there is no booking system. So at peak time it can be very overcrowded and it is difficult to relax. The second thing is that Monopol encourages using the spa facilities totally naked. This can be fine for many, but we did not like it at all to see men walking around with their bits hanging out"
