Baan Chai Nam. This is an excellent, very exclusive direct beachfront condominium with just 14 generously sized rooms available in the whole building.
Basically, each floor has just 2 units, either north or south side. All units feature natural light from 3 sides of the property, and the wrap around balconies give views directly out over Pratumnak beach, the Gulf of Thailand and Koh Larn island on the horizon!
Pratumnak Beach is a great place to be. The beach is very clean and there is a shaded footpath which winds all the way to Jomtien beach.
