Great Small Hotel
I was in Seattle one night on business and decided to try something different from the large chain hotels where i usually stay. My decision was rewarded with a very pleasant stay at this quaint boutique hotel. The staff was quick and courteous and my room, despite being an online third party booking, had plenty of space and a fantastic layout. With only 17 rooms total and only one floor there isn't much worry about noise pollution and the complementary internet had fantastic bandwidth. Also if you are a younger person the location in the heart of Belltown is perfect for nightlife and an easy walk to the majority of downtown Seattle sights.For families and those less mobile the walking distance to both Seattle Center and Pike Place market is a little over half a mile, which is by no means a marathon, but could be difficult with a family in tow.
I have two tiny complaints and neither would deter me from staying again, which i definitely plan on doing the next time I'm in Seattle. The first is that the bathrooms could use a bit of an update. Second is the down pillow-tops on the mattresses can be scratchy if you are laying in the wrong position. 
If you have the option, pass on some of Seattle's larger hotels and enjoy a night here.
