I would not call our stay in the hotel "Leisure" as first and foremost Karlovy Vary is a place for taking treatments and this hotel is a very good place to do this. You realize very soon that you're as busy as a top manager while staying at the place. There are so many kinds of treatments that one is to take that you can hardly find some time for sightseeing (well, you might not take the treatments, but this is what you're coming for to Karlovy Vary, aren't you?) The swimming pool also demands some time of yours every day. So, you should be equipped with a bathing suit when you deside to go to Savoy.
Savoy can suit different tastes as it consists of several villas of differen price levels all having different types of facilities. The hotel boasts one of the best full board services. Its cooks are highly professional and definitely not lazy to vary the menu. We were staying there for a fortnight with a new (and rather tasty, indeed) menu every day. The worst thing about the restaurant is the high price for the beverages. Even drinks are not that much expensive.
The personnel is trained very well, almost everybody trying to be as helpful as possible. Medical staff is as good as you can wish it to be. So, you should not worry about the qualifications of the people treating you.
There's something you should keep in mind if you're going to stay in the hotel: all the rooms there are rather different. So, you'd rather have a look at the room before settling down. You'll always have a chance to find a room that will suit you better. And they are changing linen once in three days. Should you be interested to have fresh linen every day, it is your problem to inform the housekeeper. Anyway, they don't mind to change every day, but won't do it on their own.
