Narrowed down to:

Bruges-Hotel de Orangerie or the sister hotel Tuilerieen.

Brussels-Amigo, le dixseptieme, or the Stanhope.

Would love some Fodor feedback.

They are both among the top hotels in bruges.We stayed at the Tuilerieen and were very pleased. It has a pool.

Brussels - the Amigo - located just behind the City Hall which faces the Grande Place. Very European, very good service, very good food.

Le Dixseptieme is small and idiosyncratic. Each room is named after a Belgian painter and each is different. I loved it, but I do recall having to duck under the ancient wood beam between the sitting room and the bedroom, not always easy to remember in the middle of the night. I finally hung a towel on it to remind me.

I know it is not not on your list but we stayed at hotel Die Swaene and enjoyed it very much. They also have great restaurant
