Tuan's home was as described - cozy and located in a great area by Fremont downtown. It's closer to the residential streets so it wasn't noisy at all, yet still convenient to all local restaurants and markets.
The bedroom is located on the second floor from the living room and kitchen while Tuan's room was on the third. We didn't really see Tuan except on the first day, so it was very private and quiet most of our time there. You'll have to climb two sets of stairs from the entrance and then another from the living room. Bedroom itself was comfortable, clean, and very spacious (big closet space). Bathroom is in the adjacent room on the same floor (not inside the bedroom). We didn't really use the kitchen and living room, but it was immaculate.
Parking is a bit tough though. If you rented a car, there's no designated parking spot but you'll need to find street parking two blocks north another residential street. This wasn't too problematic for us, but Seattle has their tiny streets and lots of uphills so take that into consideration if you have a car!
