Dear Ms. Gao,
The price is included the electricity and water. It is a small hotel only 24 rooms so there is no swimming pool. Also can not cook in the room but there are a lot of food you can buy in the walking distance. You also can walk to the sea (very close). This hotel also good for 2 persons / room. If you want to cook then have to stay in an apartment but most apartment we found in Sriracha are only 1 bed per room. We can put an extra bed but it will not be so comfortable as normal bed.
Seaview Hotel asked us to make decision soonest as they only have 24 rooms and there are Japanese guests also want to book our room as well. I think this is the good place to stay for 1 months. When you left and leave 2 persons for 1 year, we can find other place cheaper and closer to the train station (work shop). But for the big group, I prepare a mini van so we can stay in town and have more activity to do / easy to excess to food.
Best regards,
Perasak
