1/5 Terrible

Disliked: Cleanliness, staff & service, property conditions & facilities, room comfort
COVID-19 did not allow for us to visit Thailand due to tourism restrictions. Our trip was for an entire month. Four other hotels and two plane tickets were completely refunded. The COAST was the ONLY hotel that refused to refund our stay. Yes, we were provided a voucher. But, when you live 18 hours away MINIMUM by plane and are in a global pandemic... how do you deny a refund exceeding $1000+? I am HIGHLY UNIMPRESSED. This is bad business and I refused to recommend this hotel to friends or family.

Absolutely phenomenal
Stunning hotel. Pool is huge. The view from the pool and beach area is absolutely stunning. Beach has nice sand - much nicer than fisherman's Village area. Cocktails were great in the pool bar. Breakfast really good range. Nearby restaurants walkable. Cheap scooter hire via hotel and just dropped keys back to reception. Adults only. Would definitely stay again.
