We had a late landing into Koh Sumi and upon arrival at Avani, hotel staff were very warm and welcoming. Check in was painless and efficient and included complimentary drink.
The room was spacious and bright, well furnished and excellent amenities. The super king mattress was extremely comfortable and airconditioning worked brilliantly.
The buffet breakfast has a large range and was delicious, overlooking the beach.
Staff were extremely courteous and went above and beyond.
Some extremely minor issues were the pillows - being feather, did not offer support and the music from the club, located on the same premises may not be to everyones liking while they are sitting on their balconies. Music does stop about 11pm.
Wifi worked all the time. About 15mbps download.
Overall I would highly recommend and love to visit again. Words and photos do not do this place justice.
