I think that one is on booking.com .... I just press the info into hotelscombined.com, which checks a bunch of sites at one time and gives you the best rates. Sometimes, there are little mistakes and rooms are way cheaper than you would think -- even the front desk can't believe it, sometimes.

Myself, I won't stay anywhere else if Seastar Inn is available. Most hotels, there is an "unknown" factor, but Seastar Inn is the most consistent.
