The Constitution Inn
Address: 150 Third Ave.
The 147-room, clean quarters here might be a bit on the simple side, but the price is certainly right. The one caveat is that the Constitution Inn is situated a bit out of the way (unless you're planning to spend the bulk of your trip checking out the Bunker Hill Monument and the USS Constitution), though it's certainly not so out of the way that it should be ignored. Between public transportation, taxis, and your own two feet, it's fairly easy to get to the more touristed parts Boston. It's also a great place to meet the locals – the Constitution’s gym doubles as the Charlestown branch of the YMCA.
