Kind of cold, due to the fans running full speed. Also really quiet, I could hear people farting and coughing and in general that's pretty distracting. I don't expect music to be blasting, but something to help to drown people noises would be nice. My muscles get more open with a hot yoga, which I understand this wasn't hot yoga, but having fans blowing on me when it wasn't warm seemed unnecessary. The instructor was very nice and welcoming, just not the space due to the sound and cold.
