The building entrance is at sidewalk level (no stair-steps between the sidewalk and the entrance). Then it's eight steps down to the level we dance on, or there is an elevator, which I have been "trained" on and have a key to. The accessible washroom is one floor up, but the elevator goes there too. (There are other washrooms on our same level which aren't considered "accessible".)
It's common for dancers to make adjustments to the dance where necessary, and dancers sometimes ask for ideas for adjustments (e.g. "I get dizzy when I do this", or "I can't get around fast enough for this") which I'm happy to help with, just like any other questions during the class.
I hope you will come dance with us.
