I lived in Seattle for 6 years and I think it's tempting for visitors to book a place downtown because it's near the tourist attractions and a lot of the shopping.
Which isn't to say you shouldn't visit that part of the city but *staying* there can be draining because there's just so much energy throughout the day and night.
This property is located in the Central District which means that it's incredibly close to downtown (about a 2 mile walk) and a shorter walk to Capitol Hill but far enough away that you can get some peace and quiet after a busy day exploring the city. That and you have parking, which you're paying for in time (finding a spot) and money if you were to get a hotel downtown.
Where the property is located is the prime selling point if you haven't noticed.
I found it so easy to walk down to Leschi (neighborhood) for the beautiful view of Lake Washington and quality restaurants. When I wanted some legit Asian food at The International District, that was a 15-minute walk. About the same for African food in the Central District. You get the point.
The actual property itself is a converted basement that has plenty of space, along with a WASHER AND DRYER, as well as a full kitchen. I found the dining area useful in that I could get a lot of work done while also large enough to host 3 other friends for dinner and the games that are tucked away.
The *one* caution I would have is to know the area, what others might call "street smarts". Taking a midnight walk down S. Jackson Street would not be wise. However, a midnight walk toward Leschi along Alder Street would be. I'll add that there was never a moment where I felt on guard at the property as you're a good ways away from all of that. Still, if you're unsure, just take a Lyft, which most are only 2-5 minutes away.
Overall, I'd recommend the location because of how accessible it is to everything.
