The locations are great and the facility is safe and clean. However... the reason I chose this particular parking garage was because they offered coupons and discounts. Boston parking is so expensive! I figured this would be a much more reasonable way to go. The problem is that the discounts only apply for 5 hours from when you pull in to the garage. If you are there 5 hours and 30 minutes, you lose the discount completely. I used the lot at the Prudential Center yesterday and had a coupon for $22 for weekend parking. We were there just over 5 hours, so the coupon was void. I had to pay $36! I just want to let people know... BE CAREFUL!
