Jason & Courtney have THE perfect place for a family stay in Seattle. We have three little ones (5,4, and 1) and there were plenty of space for us. The views were captivating (our 1-year-old especially enjoyed them!), and we really appreciated the thoughtful touches for kids, like two pack and plays, an easy-to-use high chair, child safety locks on the doors and kids utensils/cups in the kitchen.
If you want to check out all the fun, touristy things (ferris wheel and ferries, Pike's Place, etc.) you should absolutely stay here. You can walk to everything. We also rented a car for a day to take a trip to Olympic National Park (also highly recommend!) and having an enclosed parking space for that was also very helpful.
Jason was quickly responsive to any questions we had, and he helped make our trip as stress-free as possible. Stay here — you won't regret it!
