Dangers of yoga:

Tried out the yoga room yesterday (Friday) and today, around 5pm. There were 1 or 2 other people in there besides me and I was in there for 30-60minutes. Several times the door opened with people taking a peek, but overall it was pretty quiet.
3 mats are provided. It'd be nice if they had some wipes so you could clean the mat after you used it.
Overall, a very nice amenity imho. Nobody using it for napping or sex that I saw.
