There is also a large Comfort Inn Suites right off of 495 in Haverhill. It's maybe 10 minutes from the site.
Take 125 south till you get to 495. Take 495 south.
It's right off of exit 49. If you're on 495 south, take a left when you get off and it will be on your left. If you're on 495 north I believe it's in front of you when you get off the exit.
