There's history a-plenty in this upmarket B&B, which has breathtaking views over the Glaslyn estuary to the Rhinog mountains. Its bedrooms are named after former famous residents. Shelley's Theatre recalls the poet Percy B, who wrote Queen Mab here before doing a flit, claiming someone had tried to assassinate him. Miss Hilda's room with a half tester honours Hilda Greaves, born at the Plas in 1855, aunt of Clough Williams-Ellis (see Hotel Portmeirion, Portmeirion). The William Madocks room, with an antique four-poster, is named after the man who built both the sea wall (the 'Cob') and Tremadog itself, incorporating a small house on the hillside above town into the late Georgian villa of today. All rooms have a coffee machine, mini-fridge, Welsh toiletries. Warm and friendly hosts Howard Mattingley and Mark White can recommend local places to eat and arrange taxis to reach them; there is also the option to enjoy an Edwardian cream tea in the afternoon. In the morning, breakfast, served in the dining room with beautiful sea views, sets you up for a day's exploring. It feels quiet and secluded – another world.
