Sheldon was a super host! His communication was great, and he was very responsive to requests/questions.
The place is exactly what I thought it was, which was a no-frills, budget, centrally-located studio in the U-district. Was a perfect spot for my conference located at UW.
My only gripe is that the wireless internet in the studio was painfully slow. To the point that it made doing work in the studio near impossible. (and there was no wired connection option). So if you're planning to stay for business keep that in mind. You may want to plan to work in one of the many nearby coffee shops (including one right downstairs in the same building).
Overall though, great little studio. Would definitely recommend.
