I've stayed in a number of different 'Landgasthofs' of varying standards in Southern Germany. Hotel Landgasthof Fischer has many of the good attributes I have typically found in the better ones - friendly helpful proprietors & staff, comfortable & spacious room, modern and well appointed bathroom, high standard of cleanliness, restaurant menu offering a good variety of wholesome home-cooked food, with local and seasonal specialities, and a typical traditional breakfast selection, so I would rate it above average in most respects.
Usually I find I can count on a powerful and invigorating shower in these hotels, the bathroom with its attractive tile and marble decor and spacious shower cubicle looked very promising, but actually this was my only disappointment, the shower head seems to be purposely designed to produce just a narrow stream of high velocity mist, perhaps some kind of water saving feature, but I'm sorry to say it was wholly unsatisfying.
This shouldn't overshadow all of the very good qualities, clearly the owners put in a lot of effort and attention to detail to run what is a very pleasant place to stay.
