First of all, I have rented a different studio for my yoga classes. It's quite gorgeous with wonderful views. Now my students are saying how much better it is than the last studio. So even though as a teacher we are looking for certain things, we do have to keep in mind that students may not rate as highly what we think is important. And students may not let you know that they don't like the space. So even though the last place had lots of wall space, the new place is much preferred by the students even though it is more difficult to find enough wall space in larger classes. The ambience of the studio is probably much more important to the students while we are looking at technical issues. So finding a studio that meets both needs can be a challenge.
