Hotels in Seattle can be pricey. But, downtown Seattle is compact and easily walkable, so you have choices. IN any case, whenever booking a hotel in Seattle ask about parking fees (if you have a car). Parking is usually not quoted on room prices and it can be very expensive - up to $50 or even $60 usd per night.
At the low end of the budget are a couple hostels in downtown Seattle; Green Tortoise (a dorm style backpackers' hostel) and City Hostel (a rather nice apartment style hostel with private rooms). Moving up are places like the Mediterranean Inn in the Queen Anne neighborhood or Holiday Inn. All of these are near restaurants, bars with live music, Pike Place Market (the central location in Seattle) and Seattle Center (civic center and site of many fairs).
Also consider bidding a room on PriceLine.
The best areas to stay in or near downtown are Belltown, Downtown, Queen Anne and Capitol Hill. over 2 years ago
