"My friend and I had such a wonderful stay at Yasuragi. Really enjoyed the spa facilities, and the additional classes such as yin yoga/restorative yoga at no additional cost. Breakfast was also fantastic with a wide variety of options. Dinner is more limited and difficult to get reservations. We also felt the room was basic and it can get quite noisy with people walking around as there isn't any carpet, only floorboards so sound travels quite far."
