I recently stayed at the Radisson in Chelmsford for the second time, and I wasn't disappointed. The rooms are spotless, with clean, modern linens, and the staff is fantastic. I don't think you will find a better hotel in the area for this price. Safe, quiet, and within walking distance to many things (Dunkin Donuts across the street comes in especially handy in the mornings!). I highly recommend staying here!
Pros: Clean, convenient location, great value!
Cons: Slow elevators. Seriously, that's the only con!
