Overall we enjoyed our stay, the views are great and we liked lounging on comfortable sofas, looking at the beautiful lake and the mountains. However, the place was not quite the standard we had anticipated after all the elaborate check-in forms, the many stern messages and off-putting reminders of the 'rules' and 'fines'. Everything seemed a bit 'tired', overdue maintenance on tap-ware, kitchen and showers, as well as a few minor things, like no pegs to hang out laundry (we could not get the dryer to work) and quite a few steps to negotiate without a rail.
So, yes, sufficient for a couple days but would not recommend and we would not return.
