一階と二階があり団体で行くなら二階を使いたい
一階は個人客向けで他のお客様の出入りで落ち着けないので
団体で行くなら○で個人なら他がいいと思います

There are two floors, one on the first floor and one on the second floor. If you're traveling as a group, you'll want to use the second floor. The first floor is for individual guests, so it can be uncomfortable with other guests coming and going. If you're traveling as a group, I recommend ○, but if you're traveling alone, I recommend the other floors.
