I've stayed at this guesthouse two times on business trips to Schwabach.
It is small, but very cosy. It features everything you could possibly want, but nothing more. The breakfast is standard continental. The restaurant has both traditional and international meals, both are very nice.
The hotel has a small area at the back which i figure is great for an outdoor breakfast during summer. I've never tried it though.
It is a bit outside central Schwabach so I don't think it's very good if you're planning on spending a day to see the town.
