This is the perfect stay if you're looking to explore Portland and the surrounding areas during the day! What you see in the photos of the listing is exactly what you'll get. Kristen and Kara's basement apartment is spacious with a full kitchen, what looks to be a combined washer/dryer unit (not sure since I did not use it), an ironing board/iron, lots of towels, and the standard dining table/couch/bed. There's also a very nice grocery store maybe a two-minute walk away, a convenience store a five-minute walk away, and a bus stop with buses to/from downtown a five-minute walk away. I relied primarily on public transport to get around and found this location to be pretty convenient, not to mention Mt. Tabor Park (totally awesome!) is a 10-minute drive/30-minute bus ride away. Kristin and Kara were very nice in answering all my questions.
Something to note: I expected to hear some noise and footsteps when I read that their family is active with small children (remember, this is a basement unit). What I didn't realize is how much you hear of everything. I could quite literally hear someone sigh, when they run the water, and, of course, the footsteps. If you're out during the day, then this shouldn't be an issue, and it is quiet once it gets to around 9 PM. If you're sensitive to noise, this might be something that you want to take into consideration. It's also cold in the unit even when it's super hot outside (my trip was in August when temperatures rose to the 90's, and I was sweating from walking around outside). There is a little heater you can plug into the wall, but it takes awhile to warm up and doesn't generate that much heat. The blankets were enough to keep warm when sleeping, though. You'll just want to plug in the heater before you get changed/take a shower.
tl;dr the location is very convenient if you're looking to take the bus and need to grab quick items from a convenience store, it's spacious, and the hosts are responsive and kind. It is a little noisy from the sounds upstairs (footsteps), and it can be cold so plug in the heater!
