I was greeted as I walked in with a smile and positive words. The gentleman at the desk was very kind and showed me where to find the bathroom and yoga class. The yoga class with Nancy was great! I loved seeing all the modifications around the room, she encouraged everyone to take their practice where there bodies needed it. She was wonderful. She played great music during class, too. There was a great mix that even included the Beatles! My favorite part was that during savasana, there was the sound of trickling water coming from somewhere. A fountain in the corner? Within the song? Air conditioning? I don't know, but it seemed very well planned. Combined with the sound of the light rail outside, it sounded exactly like a thunderstorm. For me, there is nothing more relaxing then a thunderstorm. Urban yoga was a wonderful place to practice, and I appreciate the welcoming attitude from the staff and the yogis. Thank you!
