Overall this is a great place and an awesome location. we highly recommend staying here if you're looking for something downtown. it's literally a block or so from Pike Public Market.
Parking in the area is expensive, but you don't need a car for most attractions. (If you do have a car, see the other review on checking in first.) We walked most places and the monorail to the Seattle Center (space needle) is not a far walk. Lake Union is a mile walk from the needle.
We recommend a hike at Discovery Park and the Ballard Locks if you have a car.
The lock boat tour is great, too. We took the tour from pier 54 to Lake Union. After that we walked to the Seattle Center, went to the top of the Space Needle before sunset, then rode the monorail back to the apartment. Perfect day.
Bainbridge island was also great, especially the Bloedel Nature Preserve. The local brewery is good and located right next to Agate which was the best dinner we had all week.
The last recommendation is the Underground tour. Hilarious stories on how Seattle first started, burned, then started again.
Alex was an excellent host and we hope to return for more adventures.
