Went to town for a show at 3S Artspace. Hotel was next door. Beautiful facility and very nice rooms. Unfortunately not really affordable in the summer time. Great for an off season trip.

Only stayed for one night for a comedy show. Was walking distance to everything downtown. Place was really nice, clean, and modern. Plan on coming back to visit Poursmith again and will most likely go back to the AC.

Property decent but overpriced for what it offers. Parking offered at Boston prices and hidden destination fees etc disappointing. In the future will choose a different resort. Location was pleasant and rooms clean and comfortable

Room was great and location awesome! We walked to Congress street - optional street pay meter parking and valet offered. The food and drinks at this Marriott were delicious! We had apps…NE clam chowder and the roasted cauliflower. INCREDIBLE. The cocktail of the day was raspberry Lemon drop - superb!
