Europe

What kind of hotels do you like (how many stars), what is your price range, and do you need a particular location or amenities? Single, double, or family room?

Munich: Hotel Uhland,
Salzburg: Altstadthotel Weisse Taube,
Vienna: Pension Suzanne

If you check the various Rick Steves books you will find lots of recommendations in each of those cities. They will come with prices and detailed descriptions, with maps and comments.

We loved The Toren in Amsterdam, it's in Rick's guide.

Here is a list of hotels in the Munich area often recommended by people on this site.

Blauer Bock
Viktualienmarkt
Royal
Uhland
Seibel
Münchner Kindl

I cannot personally recommend any of these places as I usually stay in a non-English speaking hotel in the Munich suburbs.
