This seems to be the case at all of the "rent a small workspace"-type places I've tried in Seattle, with or without regular doors. Ballard Studioworks has virtually no insulation and has a lot of noisy businesses or just people who like to blast music at concert levels. Activspace in Lake City was a little better but the floors shook every time someone moved a piece of furniture. Wework Holyoke was like working in a fishbowl with really nice furniture.

I dunno, maybe I'm just too picky. I don't want a community or all of that. I just want a place that isn't where I live that's quiet, has Internet access and bathrooms, and the rent doesn't have a comma in the dollar amount.
