We stayed 2 nights in the family room. There's a separate bedroom (a nice surprise upon arrival!), which allowed us to put kids (age 4 & 8) to bed early and close the door, so that we didn't have to tiptoe. The moment we stepped out for breakfast, room service came in and cleaned up our room. That was the fastest (& invisible!) service I've ever had! Oh, and the room is very quiet.
Breakfast is available at extra cost but with kids it's so worth it as it gives a variety of choices for picky eaters.
Everybody at the hotel is very friendly and helpful.
The restaurant is excellent - best fries ever! It offers a nice Biergarten in the backyard. Overall, really a great alternative to busy & expensive city hotels in Hannover and just 15-20 minutes drive from die Altstadt and die Marktkirche.
