I had a two nights stay in Phang-Nga and can definitely recommend this hotel for your stay here. They pick you up at the bus station and can organize any trip you'd desire. I believe, a good wifi signal, TV, AC and a good shower for this price is just perfect. You won't find 5 star hotels in Phang-Nga, so go for this.
Ah, and by the way, you will find a public swimming pool for 80 THB very close to the hotel (around 3min walk), if you'd like to swim.
If you are heading to James Bond Island, you must come to Phang-Nga and take a private trip (very cheap compared to Phuket and Krabi) in the early morning so you'll be the first one on that famous island. If you leave late, you'll find this island overcrowded as usual all over Thailand.
In total, the hosts were great! Will come back again.
