Friends,
  I will be visiting Montreal in April 2012, for hobbying purposes, and wanted some advice on both where to stay as well as recommended ladies. Many provider ads state they will only visit 4/5 star hotels, so I am looking for hotels in that class. Thanks for any assistance you can offer.

In terms of Old Montreal I enjoy Place d'Armes, Gault and the Nelligan. The St James is lovely and has amazing beds and linens.  

Downtown I like Le Germain and Hotel Sofitel. A newer boutique hotel that has great showers and bed is Chez Swann. Its charming in a modern way.
