What sort of budget are you looking at? The island is small enough that you can stay just about anywhere and visit beaches on day trips.
I stayed at 'Jep's Bungalows' http://www.jepbungalow.com/5/
Maybe not the best on offer, but clean, comfortable, next to the beach with a lovely restaurant set up on the beach. Good bars around too.
I went in late July and the weather was great

I've spent many happy nights in the Ao Hin Khok area, including places like Jep's and Naga and Little Hut. The beach is pretty good, the night scene fun but not over the top, and the prices friendlier than other places. It is where much of the backpacker crowd hangs out on Samet. From there it is an easy walk to several other interesting beaches too.
Ao Hin Khok is just one beach south of Haad Sai Kaeo, just past the entry fee booth for the "National Park." It is a short and interesting walk from the main ferry boat pier, so if you don't have too much stuff, you could even walk from the pier through the little village and past the entry fee booth.
You'll get a better selection and lower room prices if you arrive midweek. Cheers.
I don't know about beauty - Samet doesn't have any knock-down-dead fantastic landscape but I reckon Ao Pudsa/Putsa/Tubtim is the best all-round beach - pretty, quiet but only 5 minutes walk from the first of the busier northern beaches, Ao Phai .
And nothing wrong with Ao Phai either - stayed there last March, liked it. Also stayed at Jep's many years back - not bad at all.
Maybe from the point of view of undisturbed nature, a compact beach between 2 highish headlands Ao Nuan just south of Pudsa is most beautiful - but I thought the one bungalow place there was overpriced, trading on its seclusion maybe.
Samet tends to be the driest of the wet season islands in June - having holidayed at the wetter ones often in wet season I would not worry about not getting enough sun.
