We traveled last year and stayed for 10 nights. The Resort is absolutely lovely. The rooms are very nicely decorated and the bathroom was just stunning. Sitting on the balcony we were surrounded by tropical vegetation so you could already relax at your doorstep.
The beach was lovely and only a few meters away. We didn't have breakfast included. There is a good variety of resorts in walking distance so we tried something different every other morning.
Overall we were having a wonderful time, the peace resort fits perfectly into the exotic surrounding of Koh Samui and has a most relaxing atmosphere. We would happily return.
