We went to Hoian for 2 days 1 night for a short trip but we unluckily as on arrival in hoian.
We had to walked alot to find out some cheap hotels but most were full booked. Just by chance we found out Minh Quang hotel on Hai ba Trung street and had to pay 15$/room/nite. Acctually it's not valued as our money spent but that's the cheapest we could stay at that moment. With us was ok but just let other people know that this hotel there're many room without windows and the smell're terrible. But we got a good experience for now and on should book room in Hoian before you arrive. In gernal it's ok for whom looking for a cheap and a bed but for us we won't come back again.
