At Thames Inn and Marina, guests praise the scenic riverfront setting and friendly staff, but many report dated rooms, inconsistent cleanliness, and occasional check-in or communication issues, making the experience vary widely depending on expectations and room assignment.
The location is convenient to the Navy base, New London, and Mystic, though a few guests felt the surrounding area looked run-down or dicey. Suites typically include kitchenettes and some have balconies or decks, but decor and furnishings are older, noise can travel between floors, and TV or streaming was unreliable while one review noted very fast Wi-Fi. Facilities are basic: grills and laundry are available, but the docks and grounds need work, kitchens can lack supplies, and there is no on-site dining or coffee, with several guests pointing to Paul's Pasta next door instead. Expect a budget, old-school waterfront stay with trade-offs.
