Sarah's condo is smack-dab in the middle of prime downtown Seattle attractions and would be a great place for anyone who is up to walk to their destinations. You'll probably want a Lyft back to the condo, though; the hills are steep and are much easier to walk down than up.
The condo was nice and freshly cleaned when we arrived, with extra travel shampoos left out for us and some instant coffee that was much appreciated! The bed is King sized and very comfortable. Sarah also sent multiple resources for us as first-time visitors to Seattle which was very sweet!
The largest reason for a 4 star review rather than 5 is also the condo's largest attraction: the location. Because you're in downtown Seattle, you're in the midst of the city's abominable homelessness crisis. We walked by people doing drugs multiple times right next to the entrance, and there are camps scattered around the surrounding blocks. That leads us to an unfortunate first two hours in Seattle.
The check-in time is 3pm, which was unfortunate for us as we landed early and ended up waiting on a bench outside the complex for an hour for the greeter to come let us into the condo. My fiancé took off his backpack while we waited... and forgot to pick it back up. He realized about five minutes later and ran back downstairs, but by then it had been picked up by a homeless man. The man who worked the front desk was helpful in looking at the security cameras and giving my fiancé a description, so my fiancé then spent an hour scouring the surrounding blocks for his backpack (which had his laptop, iPad, and my engagement ring!). By some miracle, he eventually found his backpack in a park at the end of the block, emptied with the contents scattered beneath a tree, but nothing taken. So please beware the area and be cautious with your belongings!
For the condo itself, it's very old, small, and not quite the luxurious downtown stay I was envisioning. It also doesn't actually have air conditioning so much as it has a heating system and a standing fan in every room. My fiancé and I were pretty hot each night even with the fan running at the highest setting.
Overall, Sarah's place is really nice so long as you're prepared for the area and aren't looking for a lavish place to stay. We probably wouldn't stay here again because of our experiences with the location, but recognize that other people who are more savvy about the area could enjoy it just fine.
