The best area to stay in Portsmouth is around the historic waterfront, particularly near Thames Street and America's Cup Avenue.
This area is the heart of Portsmouth's visitor experience, offering a blend of historic architecture, boutique shops, and a wide array of dining options. It's very walkable, allowing you to easily explore the cobblestone streets and enjoy the views of Narragansett Bay. Bowen's Wharf and Bannister's Wharf are central to this district, known for their unique shops and seafood restaurants.
Couples will find this area particularly appealing for a romantic getaway. You're within easy strolling distance of many fine dining establishments and charming inns, superb for an evening out. The proximity to the water also offers opportunities for scenic walks and boat tours.
For those looking for a more relaxed, residential feel, the area just north of downtown, near Washington Square, is a good option. It offers a quieter setting with elegant historic homes, while still being a short walk from the main attractions.
