We stayed in a studio at BCV a couple weeks ago. Laundry is on 4th floor near elevators. There are 2 washers and 4 dryers (but one dryer was out of order).
One washer was in use when I got there (around 2:30 p.m.), so it took longer than I had hoped to do laundry since a had a couple loads. It was a busy place and had a waiting line for a washer when I went to get my last load out of the dryer. This was late afternoon, so it appears people were doing laundry while taking a break from the park.
The room is certainly large enough to add more washers and dryers - wonder why the don't?
