Sorry , that booking is unavailable . Perhaps another day or a shorter stay would work for you ?
inform((_:search,stars,'4');(_:search,type,'Hotel'))

Can you suggest another place , is there a hotel with 4 stars in that area ?

I 'm sorry but there are no 4 star hotels in the east , but there are quite a few 4 star guesthouses . Would one of those interest you ?

user
Yes . I want to book one for 5 people and 2 nights starting from saturday .
