This one is super close to the Night Market, a super authentic local night market with local Thai prices. The building itself and walls have already aged and it is not a modern hotel anymore, although the reception area is well maintained. AC and TV worked well in the room (however no SmartTV). Mattress was good, rather a hard one, which is common in Thailand and which I do prefer. Staff was professional and spoke very good English.
The shower and bathroom is as on the pictures, clean and comfortable - actually the strongest point of the rooms, together with the fridge and selection of fairly priced minibar items. Cleanliness could be a bit better, e.g. apparently nobody is cleaning under the bed (found some clothing items of previous guests). The LED installation behind the bed is also quite dusty, which is a design mistake and obviously hard to keep clean - this could be designed differently after a renovation.
Remark to hotel staff: in order to keep rooms cool, which are exposed to sun, it would make sense to close the curtains before a new guest arrives. This would also save you AC cost and make the arrival even more comfortable.
Future guests: take note of a 300 THB deposit in cash, which is mainly for the minibar I believe. The hotel informs about the deposit in the terms of Service on Trip.com, which is good. I got the deposit back after staying one night and after deduction of consumed items.
All in all, considering the price and location, I would come and book again, especially if you are staying just 1-2 nights in transit. The hotel is also walking distance to Phantip and Phangan Tour 2000 bus offices, which provide transfers to e.g. Koh Samui or Phuket Town.
