Dat and his family is a wonderful host. They are extremely helpful and accommodating. They ensured that I feel at home in their place and even gave me tips on which transportation to take for my tour. :)
The location of their house is also strategic since it's close to train station (Ojima Station S15) ATM, drug store, convenience stores, and even McDonald's. :)
You will definitely enjoy your stay at Dat's place. :)
