So we stayed at the Cosi Samui Hotel for one night so we could find somewhere else on Chaweng Beach itself. When we arrived we were greeted by the staff who were very forthcoming and friendly, we were given 2 vouchers worth 100baht each which could be used for whatever we pleased...at the hotel café 😋. We were shown to our rooms which was very helpful and we got a thorough explanation on the different amenities of the hotel and surrounding parties/festivals (we were lucky that we arrived on the day of the Samui Festival!). The hotel was in a prime location being beside the main strip of Chaweng and a 5 minute walk from the Chaweng beach.
The room itself contained everything you wanted i.e. a comfy bed (nicest we've had in Thailand so far), great bathroom with an even better shower, usb ports and sockets throughout the room, a smart TV and a small fridge. There was a pool upstairs on the roof top which was really big and quite secluded.
Overall the hotel was fantastic, the staff were great, rooms were everything we wanted. Worth every penny. If you're coming to Chaweng for a few nights we highly recommend the COSI Samui Hotel. 5/5 😁.
