We were a group of 9 during our stay.
It is a nice place, convenient from the train station and has good amenities.
TRAIN: Some comments here says that you can hear the train passing by. Yes, you can here it but not too loud. But during around 12 A.M. onwards, you won't be able to hear any trains so you can sleep well.
PILLOWS: It is soft but maybe too high. Some of us wasn't able to sleep well because the pillow is too high/thick. Our neck was aching when we woke up. Maybe they should change the pillows.
SHOWER: Very low volume of water in the other shower room. Maybe they should adjust the pump or something. But you can still take a bath.
CURTAIN: We expected to see a curtain inside the living room. But there was no curtain. Though there are blinds that you can use.
NOISY NOTICE: You will be fine 50,000 yen if the neighborhood will complain of too much noise. BUT it doesn't mean that you can't laugh out loud with friends or play something fun. Just minimize your voices and everything will be fine.
OVERALL: We enjoyed our stay here. Those were the minor problems we encountered but we LIKE the place in general because of CONVENIENCE, AMENITIES, GOOD FOR LARGE GROUP, NICE PLACE, SPACIOUS LIVING ROOM AND A VERY RESPONSIVE HOST.
We will surely book again on the future.
