This is a very nice location with easy access to explore downtown Seattle (Bus stop is 10 minute walk). Very spacious living area, bedrooms not so much. The (one) bathroom is attached to upstairs bedroom and accessible from the far side of house, through the kitchen (away from basement sleeping areas).
Basement is comprised of bed #2, a small sofa & additional futon (w/mattress topper) next to a washer and dryer closet. My 6'1" son found the low ceilings of basement to be claustrophobic. In contrast, upstairs is very open and airy. Plenty of room to add a blow up bed there!
Plenty of new towels and wash cloths, but needed to scavenge for sheets and blankets/pillows for futon. A comforter and pillow covers (and bed made up and ready) would have been appreciated.
It's a great little area; we enjoyed exploring the neighborhood and walking over to Kerry Park for awesome views of the city! However, if you're booking in hopes of a water view, request the top unit. The view of the water is really only accessible from the uncovered deck, and since it was rainy/wet all week, we didn't get to enjoy that aspect unfortunately.
Trader Joe's is a short Uber ride away, and right across from Zeke's Pizza (went there on host's recommendation. Two thumbs up!). Host was friendly, available via text and very responsive.
Second story is rented as a completely separate Airbnb unit. There was overwhelming noise from animals on the wood floors in the unit above us during our stay. Interfered with sleeping in master bedroom. Wifi is terribly slow--be prepared with a hotspot if you need to work on your laptop.
There was a nice welcome basket of assorted snacks, coffee, creamers and bottled water (Brita in fridge was a also a nice touch), and an array of condiments and seasonings. Zero cooking oil, however. Kitchen is open and well-appointed but no toaster that we could find. Small umbrella and hair dryer is provided for guest use, as well as what looked to be a folded up treadmill if you're feeling ambitious! (I would double-check that with host!) All-in-all, a very bright, modern and clean place to stay while visiting Seattle!
