Nice room, not big but doesn't waste space. The casamia flagship store is in the same building, and there is also a restaurant. It's located really close to garosugil, so there are a lot of cafes and restaurants in the area, besides shopping opportunities.
Decoration is their strong point and service was nice, although a bit slow maybe.
I tried to go there for breakfast on my last day but there were no waiters, apparently only the breakfast buffet was available, but it is 25,000 per person, and it didn't look worth it
