Hotel Helvetia is one of the many hotels (all pretty similar in range and facilities) dotting the Lindau harbourfront.
The hotel is modern, clean and the staff is quite helpful. It is also very quiet, despite the central location.
One of the main "pluses" of the hotel is the very pleasant rooftop spa area but don't let yourselves be tricked by the term "infinity pool" used in the hotel description, because what they have up there is just a large jakuzzi.
The spa are in the basement is less nice, it's not very relaxing due to the very bright spotlights, the pool is tiny.
I had lunch at the restaurant and I wasn't very impressed, I think it's expensive and the quality medium. Maybe the dinner menu is more appealing..
All in all I think this place deserves 4 stars read more
