Staying at Kate's house was such joy, I loved it. Beautiful clean, quiet, luxurious house with a garden, in a gated community (aka 'village') with a gym and a gorgeous swimming pool. Right outside of the village gate there is a 7/11, and a few small stores, and restaurants you can walk to, as well as a bus stop (Green Songthaew bus) that will take you to downtown Hua Hin in 10-15 minutes for 10 Baht.
Kate was amazing, she was the best host I met on airbnb.com. She was always willing to help with a smile on her face, even came from Bangkok to pick me up at the Hua Hin train station, and help me check in. She also arranged for a motorcycle rental company to drop off a motorcycle at the house which made getting around that much easier. I cannot speak highly enough about Kate and the house. You will not be disappointed if you stay here.
