There are quite a number of places in Boston. Some are high profile and feature some of the world's great names in Jazz but here's a few links for you:
The high profile establishments are Regatta Bar and Scullers
Others that have a more local entertainment are:
www.wallyscafe.com/ Ryles Jazz Club (212 Hampshire St. Cambridge; 617-876-9330). The two-floored venue hosts both live music on the main floor and dancing on the second “dance hall” floor. Jazz artists performing at Ryles are both nationally established and local musicians.
Westin Hotel Copley Place Boston

http://marriott.com/property/propertypage/BOSCO I live an hour outside of Boston, never played any of those venues. But have been to them a number of times thru the years. The hotels listed all have piano bars, they will probably be your best and are in the nicer areas of Boston. Good Luck.
