Looking for pet friendly hotels
Check out http://www.pet-friendly-hotels.net/ . We stayed at Marriott Residence Inn on Deer St and I know I saw a dog there. The Sheraton is also pet friendly. These hotels are downtown Portsmouth and youcan walk anywhere downtown from these hotels. There are also some pet friendly hotels on the outskirts of Portsmouth if you don't mind driving into downtown. There is a very reasonable parking garage on Hanover St.
