I'm still be missing their place. They have a good view (I was stayed at middle floor with my family), and they let me know what I should concern about and what we must follow the rule. It seems that the rule is strict but I had never felt like that. Above all, my family was satisfied and they said when we were there is the best of their travel schedules.
I've experienced some guest house by Air BnB several time with my friends whenever I have a trip in this country, some house has not enough amenities, linens and bed sheets ect. So that I always bring my linens and some amenities for shower. However, if you wanna decide to stay her house, you don't need to concern about it at all. They prepared good quality amenities for guests.
Thank you Sarah for your kindness and hospitality.
