This site gave me great websites like venere.com to search for hotels in Italy. Anyone recommend any other great sites for hotels all over Germany?
Thanks

That's a little broad. Can you narrow it down to a region of the country or perhaps even a city?

www.hrs.com is a good one. It's the one that the German railroad website (www.bahn.de) links users to.

Where will you be heading?

I will top my trip report for you. We just got back from Germany and I wrote detailed reviews on hotels in two cities (Rothenburg and Bamberg).

It's not a website, but I have almost always had good luck with the hotels recommended in Rick Steve's books. The downside is that there are often MANY Americans at these hotels so you won't meet as many people from other areas of the world.

Try hotel.de - I got a good rate for a single in Cologne that was a touch less than what the hotel itself was quoting.

www.hrs.de

Great advice here.
www.hrs.de
and
www.hotel.de

are dependable and good booking sites.

Additionally, I'd also like to throw in
www.de.lastminute.com

www.bookings.de is a good one with lots of hotels and good rates.
Just click the British flag for english.

For our trip in May, I checked each city's website and looked under Tourism (or Tourimus in German) to see the hotel listings. Some of the hotel websites are in both German and English. I then contacted the hotels that interested me by email to get their best rates.

If you are going to Bamberg, for instance, just look at www.bamberg.de, or for Cochem, www.cochem.de, etc.
