Had a very enjoyable stay. The location is great - very easy walk to downtown Fremont area, which has a number of great restaurants, coffee shops, and just a lot of character.
Very easy access to the highways and U Dub. The place was spacious and really nicely decorated. Yooeun was a great host -- we only had one reason to contact Yooeun during the stay, but Yooeun's response was immediate and helpful.
The one note I would say is that the place is above a busy intersection, and the noise from the street traffic was noticeable. If you are a light sleeper, a pair of earplugs is probably recommended.
Otherwise, would love to stay here again when we next visit Seattle!
