We stay at the Belltown location and it was really nice and cozy apartment.
The place had lot of amenities and the loft feel was really nice. I did got locked out once and their support staff was really helpful and was able to resolve the issue the next day (lock code for the front door was not working).
Main reason for me to book this place was to work from downtown office which was a 30 min walk and it was really fun to walk everyday thru different coffee places, the Pike market or different restaurants for dinner.
The only issue that I hope they fix is the internet speed, some days I had to take early morning calls and if me and my partner both were on zoom calls the internet would die or really struggle to work.
Overall it was a fun place to stay and worked pretty well for me. I would come back and stay.
