I chose this place because of the location - it's near all the major transport links - buses to Space Needle and the Museum of Flight, Bolt Bus, Amtrak and even the link to the airport. Downtown and Union Square. There are many affordable Asian eateries and a great Japanese supermarket nearby, so it's one of the most convenient locations I've stayed at.
The "room" which is basically a shared sleeping space is basic but clean and spacious, compared to a hostel. Lights off at around 11pm, so it suits those who want to sleep and rise early. The air conditioners were working great, as it was pretty warm in Seattle.
I read the other reviews which warned of noisy neighbours and the area feeling unsafe at night but it was pretty quiet the 2 nights I was there, even though it's next to a main road. There are quite a number of homeless people around - they hang out near the convenience store next door but don't bother you, so it wasn't threatening.
Tips: Check with them whether the Wifi was working (it wasn't), so have back-up ready and bring your own towel.
