Fantastic hotel, a bit far from downtown
I stayed here for a few nights on a business trip. The office was in South Lake Union, so the hotel was within walking distance. I was pleasantly surprised by how comfortable and well-decorated the rooms were, and all the hotel staff I met were helpful and personable. Overall, my experience with the hotel itself was great.
The location is a bit odd, and feels a bit run down; when I was there, there was a ton of road construction going on, and there were some streets which were closed off even to foot traffic. It's not a very walkable area in general, because some of the streets pass under or over each other, so you have to walk long distances where on the map it seems as though you can just go around the corner. There are a few nice places to eat within walking distance, though (including an amazing Greek restaurant), and Westlake Ave is about a 15 minute walk. The downtown core is farther - it took me about 40 minutes to walk from the centre of downtown to the hotel. I did not mind the location at all, but I think it's important to be aware when choosing this hotel.
I would definitely stay here again on a future business trip to Seattle.
