Lovely, clean hotel, conveniently located to all of downtown Portsmouth. Enjoyed drinks on the roof. Staff was super friendly and welcoming. Weird complaint: HATED the coffee machines in the room. Everything else is so thoughtful and deliberate, a weird offbrand machine that filters boiling water through single use plastic was just ick.
