I recently spent 2 nights at this hotel with my wife. We were part of a 20 person group attending a trade fair at the local Friedrichshafen Messe. Unfortunately our experience there were a great deal worse than those reported in the other reviews here.
It began when we checked in - the owner was MOST unfriendly and we felt particularly unwelcome. The room was small and very basic, but it was at least clean. And we gained a lot of amusement reading the hotel and other local info provided - the English version being very similar to some I have found in China.
When we gathered with the rest of our group in the restaurant later that evening, the service provided by the waitress was less than acceptable - she was aggressive, rude, loud, and overall gave us the feeling we had somehow become part of a German Fawlty Towers production. And the standard of the meals was very poor. What was advertised in the menu as a local specialty (and NOT inexpensive!) was dry, overcooked, and the chips smelt strongly of old fat. We were unable to eat our meals.
Returning to our room around midnight we discovered that the heating had been turned-off some time before and the room temperature unacceptably cold.
Breakfast next morning was a simple buffet selection typical for Germany. However, some of the pates and the fruit juice had gone completely off. When guests at a neighbouring table complained to the owner about this he advised that this can happen when there has been thunder during the night (There hadn't been...) but made no attempt to have the "off" items removed from the buffet.
We returned late from the trade fair (Around 12PM) to discover our room had not been serviced. We were the only ones of our group to have this. However others, although their room had been serviced, had no towels. The owner did apologise for this in the morning.
All in all this was a hotel experience from Hell, and there is NO WAY I could recommend it at any price.

The owner speaks good English and is very hospitable as is his two dogs and the other staff members. The rooms are clean with Pine furniture; they are not large, quite basic, but perfectly adequate. The beds are firm, pillows thin, but clean and once again adequate. The rooms have a small TV. The bathrooms generally have a shower, with glass doors, which works quite well although the pressure will not knock you over. There is heating but no air-con.

Continental breakfast is included in the bargain price and is very good. The restaurant also serves very good food of an evening (steak, Fish, Goulash) at a very reasonable price. There is also a bar. The Zeppelin Museum, School Museum shops and lake front are only 10-15 minutes walk away. (Why not splash out and take a Zeppelin flight while you are there, these are pre-bookable on-line).

The Hotel is Not outstanding as such, but as a budget choice it is excellent value for money. I’ve given it four starts not because it is a ‘four star’ hotel, but it is very good for those that essentially want a B&B. It is probably better than most UK hotels at that price if you can find any.

Combine this Hotel with a Ryanair flight from Stanstead for a cheap weekend away!

we stayed at this hotel for just the one night. we found the location was fine, it was 5 min walk to the lovely lake and the main shopping area. the rooms were clean and bright and the staff (poss the owners) were very welcoming and friendly. the breakfast was the standard continental, bread, cheeses, hams, cereals ect with various juices, tea and coffee. all in all a very pleasant hotel in a nice town

We booked two rooms, one for myself and my partner and the other for my ageing parents. The hotel was very clean and friendly. Rooms were small but very nice and the bathrooms recently refurbished. The brakfast buffet had excellent variety.
