Beautiful hotel in an extraordinary location and the staff is great. I was lucky and got a huge room. Only some minor complaints:
1) The water temperature of the shower was impossible to control, so I burned myself several times and decided it was better to take baths.
2) The breakfast is very disappointing for such a great and health focusing hotel. Products are not natural and there is a very limited selection, especially of greens, but also of other things, and no diet products.
3) I tried ordering a burger sandwich at room service for 16 euros, but ended up paying nearly 40 euros (incl. tip) for it as they misunderstood (strangely) the order to be a main dish burger of 21 euros and a tuna salad of 16 euros. The burger was poor and likewise the small salad. The delivery did not make sense at all, since it in this case should have been two salads (as a salad also should have accompanied the main dish burger).
