My family had an excellent stay at Yooeun's place. The second bedroom is perfect for two kiddos (hot tip: bring a travel blackout shade to throw up in the window to allow for a longer night of sleep for littles - the natural light in this place is amazing but isn't ideal if you're looking to have your kids sleep in a little!) The bed in the master is super comfortable. My husband has a hard time sleeping while we travel because he has a bad back, and this bed was a 10/10 for him.
The space itself is really cool - fun angles, great light, and tasteful (seasonal!) decorations. The location is very walkable from everything in Fremont and offers access to several different bus lines. Easy walk to the Zoo, and not a bad location to head out for a run around Green Lake (about 6 miles round trip from the apartment).
Yooeun was an excellent communicator, and even though we were too busy during our trip to do much checking in with her, she was really great about checking in with us.
Overall, will definitely try to stay here again next time we're in Seattle. A total gem!
