I spent close to three weeks in Koh Samui and in this apartment. The apartment is very nice and is located on a nice spot on the island, quiet but close enough to many areas. The Replay apartment complex in general felt safe and all the facilities were modern and well functioning. The owner was a friendly and nice person. I had no problems with anything during my stay. Cleaning was done between 5-7 days and was exceptionally well done.
If I come to Koh Samui again, will definitely consider this place for my stay.
