I booked the place for hosting my family (3 persons) during the holiday break. They loved it. The location is great, next to bus 62 to downtown + next to I-5 to/from the airport easily + in the middle between two great neighborhoods (greenlake / roosevelt) with restaurants and grocery stores around. Very convenient!
The place has multiple floors, and stairs (I would not recommend if mobility issues), so everybody could have their own room and bathroom for privacy. The kitchen is well organized and you can actually cook there if you need (compared to other places I've seen where the stove is mostly decorative). Rooms are spacious and have lots of closets for longer stays.
All in all it was a great experience. Jam was super responsive and thoughtful, I'll book that place again for sure!
