House on the Lake
I regularly join my wife on business trips up to Seattle for a change of scenery and to check in on clients I also have in the area. We stay at the Residence Lake Union exclusively for good reason. It is our dog Jo's favorite hotel. Really. He loves to travel and the staff now know him as a frequent guest. The best part is the pet charge is only $10. But seriously, this property feels like a getaway in the heart of one of the world's great cities. Easy to find, comfortable and clean, the Lake Union is a welcoming place that puts Seattle at your fingertips. 
Don't confuse this Marriott on Lake Union, with the Courtyard Marriott on Lake Union. We have stayed at the Courtyard and it is not the same caliber. We actually pass right by it with the dog on our morning runs around the lake. It looks tired compared to the Residence. The trolley also run right outside the door at the Residence, for the quick trip downtown without having to hassle with parking. There is great food steps from the hotel, some right on the lake. Serafina and Pasta Freska are both close and four-star Italian restaurants. The hotel has their breakfast bar and evening snack and wine tastings which are better than average, but for a great breakfast head up Eastlake to Louisa's Bakery and Cafe.
The corner rooms have bigger decks with great views of the lake and north skyline. The kitchens make it easy to eat in. We make a stop at Whole Foods or PCC Market over in Ballard and stock up on finger foods to go with a glass of NW wine or beer out on the deck. We even invite local friends over and entertain because It is all too easy, like having your on house on the lake...
