8/10
Hotel Sonnehof is located in the quiet city of Dietzenbach, a commuter town not far from Frankfurt. Hotel premises are just fine, not big, not too small to be uncomfortable. Internet is a disaster, depending on where you are located within the hotel it goes and come all the time and they only give you one ticket for one device (if you want more it is 5 eur/per ticket/per day)
Breakfast is better than average and not a big price at all for what they offer. Restaurant is also fine and good it is because there is nothing else in the whole town for a dinner.
