Decide if you want to be downtown or in a smaller neighborhood. Downtown accommodations can be convenient, but they're also noisier and busier. Smaller neighborhoods are more remote and peaceful. In Seattle, the Green Tortoise is located in the heart of downtown, just a one mile walk from the Amtrak train station. Hostel Seattle is in Ballard, which is about 45 minutes by bus (take the 17 or the 18) from downtown Seattle. Hostel Seattle offers a view of Shilshole Bay and is located on a public bike and walking path that leads through Fremont and into the downtown area.
Expect to pay $25 to $40 for a bed in a dorm room with four to twelve people and $60 to $70 for a private room. The prices are higher in Seattle than in many other cities because Seattle has so few hostels. Also, be aware that hostels in downtown Seattle cost more than hostels in the surrounding towns.
Know that size matters. Choose between a larger hostel, such as the Green Tortoise, and a smaller hostel, like Hostel Seattle. Pick a large hostel for the best amenities and a big group of fellow guests. Small hostels generally feel "cozier" and more like a home away from home.
Call to make a reservation. Book in advance, especially on weekends. There are a limited number of hostels in Seattle and they fill up quickly. Most hostels require a credit card to secure a reservation. This is the perfect time to ask questions about directions, parking and check-in and check-out times.
