I could rave about this place forever- but, as everyone else has already, there seems little point. So I'll keep this sort and sweet.
Our room was more like an apartment - so spacious, comfy furniture, lovely kitchen, great bedroom and humungous shower! (My wife said she would have loved a bath, too).
The best surprise, however, was the "help yourself" fridge at the bottom of the stair which is always fully stocked with softdrinks, cheeses, ice-cream etc. There was also free wine (Australian!), cereals, fruit, muesli bars etc.
We chose to have a breakfasts delivered to our room and they were so sumptuous.
The B&B is close to the Zoo and a pleasant drive into Seattle (a wonderful city). We couldn't speak more highly of the Chelsea Station. It was a highlight of our 6-week road trip down the West Coast and Mid West.
