Tracy and Seth were fantastic hosts who had provided an excellent lead-in to our stay with offers of recommendations (many of which we took in tandem with recommendations our own Seattle friends gave us, and they were all excellent!). We would definitely stay here again if given the chance!
The space is on the smaller side, but not too small, which worked perfectly for us. It's perfect for up to two (maybe three) people to hang out in, or for more to use as a home base or as a work-from-home workspace. (If you are very tall, just know that the ceilings are lower and someone who is 5.5' tall can easily touch them while flat-footed, as this is a basement-level in-law apartment.)
This being said, the space had two twin beds and a pull-out queen mattress sofa and felt pretty spacious even for its smaller size. My friend and I never felt like we were tripping over each other in our own spaces or when we were both in the dining/kitchen/living area.
The kitchen, bathroom, and bedroom were stocked with basics like salt/oil/spices, utensils/servingware, a fridge, a hair dryer, some toiletries, an iron, and ironing board. There is a washer and dryer if you find yourself hiking or in need of a freshening up of clothes, and the bedroom has two bookshelves stocked with a variety of books, ranging from kid-friendly fare, things about Seattle to help you with your stay, and to some more standard fiction, non-fiction, and academic books that reflect Seth and Tracy's careers as anthropologists. The wifi is really solid for basic streaming or web surfing, though we didn't try anything like a zoom call, but I'm sure it would be fine if you needed that. The welcome guide comes with all you need to know about the idiosyncracies of Seattle's Trash/Recycle/Compost program, among other helpful tips and tricks and recommendations for the space, as well as the quiet hours (which are really reasonable!).
The neighborhood is quiet, which is perfect for spending time out of the hustle and bustle of Seattle Center, but is also a quick 10 minute bus ride (or 30-ish minute walk) to Ballard, Fremont, and Wallingford, all neighborhoods we loved spending time in during our stay. The place is also about a 20 minute bus to U-Washington, with some direct bus lines with 30-ish minute trips downtown (The Space Needle, Pike Place, many of the larger theaters like Seattle Rep, etc.) only a five-minute walk away. Depending on who you're with or what your sightseeing or work goals are for the time, you're a ten-minute walk from the Woodland Park Zoo and Woodland Park itself as well!
Seth and Tracy are really there to make sure your stay goes smoothly, and are responsive to any needs you might have, whether that is recommendations or an issue/lack of resources within the space (like something not working properly so they can fix it, or if you run out of something like toilet paper, which in our case we got ourselves just due to timing and not wanting to be a bother (and we were fine with contributing!), but which they truly wished they could have helped get so we wouldn't have to spend our money on that!).
Basically, this was a 10/10 would stay here again opportunity. And as long as Seth and Tracy would have us back, we would definitely do so. It was such a great deal and a great atmosphere for what we needed, and those neighborhoods nearby were my favorite parts of my stay (aside from, you know, getting to see my friends tie the knot!).
