Three nights in Portsmouth and three weeks in Portsmouth call for a very different kind of stays.

A few days of meetings. A week visiting clients. A month settling into a new role. The longer you’re away, the more the little details matter.

A walkable location. Space to unwind after a full day. A kitchen for the mornings you’d rather stay in. The comfort of having a place that feels like your own.

At the Treadwell Mansion, historic Portsmouth character meets modern hospitality, with accommodations ranging from king bedrooms to spacious suites and apartment-style residences, all units include a full kitchen.

Whether you’re traveling for business, relocating to the Seacoast, or simply planning to stay a little longer, where you stay can make all the difference.

A weekend that meant more than basketball 🏀

As summer slips away, we’re looking back on one of those nights that makes us miss it just a little more.

We were proud to welcome the R-FF to the Skyline at Treadwell to kick off the first annual RFF weekend. Bringing together friends, partners and the Portsmouth community around a shared purpose.

From our rooftop to the EV3 Eli Robinson tournament and The Duncan Robinson Basketball Clinic, the weekend raised more than $170,000, including $100,000 in grants to five local mental health organizations.

Grateful to have played a small part in a weekend built around community, connection, and meaningful impact.

Heart. Mind. Body. 🌅🏀

Portsmouth’s art scene is shaped by the people who create here, curate here, and open their doors to our community.

This is the start of something we’d like to do more of at the Treadwell Mansion. Using our platform to introduce our guests and followers to the artists, galleries, and independent businesses that make downtown Portsmouth such a special place.
