We planned to go to Ko Phayam and found that the hot Springs in Ranong was worth visiting. We selected Raenong Botique Hotel for two nights to enjoy the hot Springs. We were met by very friendly and accommodating hosts, and even if English communication was a challenge, we got all the help and assistance we needed. The room was nice an clean (the hotel is just over a year old and well maintained).
A good Thai breakfast was provided and the location is practical, and within walking distance from several restaurants.
We can recommend the hotel, and suggest you spend a day in Ranong and look into its surroundings.
