Hello. A family of four (parents and two children) looking for a 3-bedroom house or condo in or close to Hua Hin for the period from 28th July until 10th August.

Will (most probably) be renting a car for the period so transport isn't really a problem but don't want to stay more than 4-5 km outside Hua Hin.

Any suggestions? Anybody looking to rent a house/condo for that period?

Budget: About Baht 15,000 for the 2 weeks.

Any luck?

That sounds like not a lot of money, only 1,000 baht / day for a three bedroom place for two weeks.
