We (family with 9Y kid) booked the hotel through their webpages (http://www.goldenerloewe-guenzburg.de/), when we were looking for accommodation close to Legoland.
They communicated in English, even via e-mail.

It's a nice small hotel (or rather pension) with restaurant on the ground floor and parking. We've got a nice blue room under the roof, everything was very clean, excellent service.

It's a family owned and you feel like a member of the family, especially on breakfast w/ kids, since kids have their pencils and they can play during the breakfast! Nice and pleasant. You can also buy a ticket to legoland there, although it's better to do it online, since you get better discount

We didn't try the restaurant there, we went to the center for a dinner.
There is also a supermarket close to the hotel.

PROS: Close to Legoland, easy to book, English, quiet, family friendly, excellent service, free parking in front of the hotel
