"It has not been renovated recently, somewhat overpriced for what you get. Definitely has a "cheap motel vibe", but not surprising for Motel 6 at ~100 a night with fees and taxes a little on the high end. I'd rate it more a $70-80 a night all in. There are other places that are nicer more upkept in that ~$100 price range (Howard Johnson, Anchorage Inn for example), but they require a deposit for incidentals. Usually ties up another $100 for a few days after checkout. Not ideal for a place to lay your head for a night or two.
There are other issues, for example the smoke alarm was plugged up with toilet paper and the room smelled like it had been smoked in. The hallways smelled like weed. Not a big issue to me as a solo business traveler. But if you have kids or family or have sensitivity to those things it might come off as a bit rougher. It's in a nice area though for Portsmouth, just overall has a cheap/rough vibe.
Overall the bed was fine, the sheets were clean. The room was clean, except for clearly cosmetic issues (rust on bathroom hinges, spackle on the walls/bathroom fixtures) it's a place to lay your head for a night or two."
