Great rooms, spacious and clean. Perfect for two people staying a couple of days or more.

6.0

The room was spacious and clean. The king bed was comfortable and perfect for two. Perfect room for two people staying for 2 days or longer.

Breakfast felt very low standard. Paper plates. Plastic cutlery and cups. Talk about unsustainable. Really Marriott?? Food choices were just barely acceptable, it felt like eating breakfast at summer camp. Get 'em , get 'em fed, get 'em out. What happened to your high standards? We were with 3 people, so one of us (me) got the pullout couch. This bed was far too soft and dipped in the middle, so I slept on the couch which was much firmer. Make sure you are nowhere near the elevator which makes quite a lot of noise, and make sure no one on your floor has a dog (especially a barky one).

Modern clean hotel in downtown Portsmouth

10.0

Well located in downtown Portsmouth, this hotel was full for the upcoming week so we could only stay one night. Clean, great beds, Free breakfast was decent but only turkey sausage patties, they need to offer pork sausage and certainly a bacon alternative. Also coffee was ok but Holiday Inn Express I stayed in Wells Maine had machines that ground the beans for each cup, that would be a nice upgrade for Marriott.

8.0

Loved the location. You can walk to so many shops and restaurants. The bed was comfy. The suite style rooms were great.

When we arrived on Friday there was very loud construction behind the hotel, which was basically the view from our room. Luckily it was done in a few hours and they weren’t doing it over the weekend. The complimentary breakfast buffet was not great and the coffee there was very bitter.

Mediocre

6.0

Biggest plus-close to the action in town but the negatives, unfortunately, outweighed this. Was not warned in advance of construction next to the hotel-noise, street closures leading to the hotel, and dug up streets. It was extremely difficult to get to. Parking is expensive. Bonvoy loyalty was not acknowledged at check-in. Room did not have normal Residence Inn amenities-no popcorn/snack, refrigerator did not make ice, could not control temperature of the freezer drawers so one drawer did not freeze. No lotion, make-up remover cloths. Breakfast offerings were consistent with most properties but coffee station had cold, unreplenished coffee by afternoon. Bathroom floor in accessible room was filthy. Worse of all, no Marriott in Northern New England that we've stayed in, have NESN TV channel so forget about watching a game. Not the worse property, but too many negatives for the price paid to recommend.

Terrible

2.0

The room had dirty sticky floors, the box spring cover was exposed and shredding, we overlooked a construction site that was loud with trucks, all in all it was horrible. Plus the put us in the room the furthest from the elevator.
