The staff gave us a warm welcome and were friendly and helpful throughout our stay. I forgot to specify in the booking that I don't want a smelly room, but they moved us to a non-smoking room without any fuss.
The hotel - like all in Si Racha - caters to many Japanese guests, so the main restaurant is a small and decent Japanese affair. The staff allowed us in even though it was near the 10pm closing time and didn't hurry us. Same experience at breakfast - best on the weekend if you like sushi freshly made to order, but the Japanese and Thai buffet selections were good (Western fare nothing special, but unless it's a 5* hotel I prefer the local food anyway).
Location is nothing special but not far off the centre and a free shuttle bus is provided to various places nearby. You can experience street food at the end of the road and there's a choice of massage shops and the inevitable 7-11 opposite.
WiFi is free and seemed to be working ok, although I used 4G most of the time because I was too lazy to log in. We also had free coffee from the reception and use of the swimming pool. I think they do a good job of providing a the little details to make guests comfortable.
Rooms are simple and fairly comfortable, but my one real complaint is that the curtains aren't thick enough! We were near the corner of the internal courtyard (11th floor) so nice and quiet, but light comes in through the adjacent corridor all night and it's enough to walk around the room by, even with the curtains closed. I ended up using the eye mask from the long haul flight as it was the only way to sleep.
Despite this, we were happy with the hotel and will probably stay again. Recommended, but bring an eye mask - and to the hotel owners, please buy some thicker curtains!
