Royal Panerai Hotel Chiangmai in Chiang Mai City

It is an ok hotel and the room is spacious and the bed good—-but there were some issues. There was some noise from an outside air conditioner. Also there was a balcony that was locked and in a run down condition. I attach a photo of this. At night there was a light on the balcony that could not be turned off, although the curtain could be pulled across to block out some of the light. I also I could not book for further days. I initially booked for one night. Further nights were not available. But in the morning I was able to book for a further night on trip.com. I was in the same room but they did not service the room and only left two bottles of water outside the door. So the next day I wanted to book again but it was not showing on trip.com. I was then told I could pay in cash but the price was double. So I moved to another hotel about a kilometre and a half away. I then looked at trip.com and the room was available at the same price. I am very displeased about this as I should have had the option of extending at the same price. I would like a response from management as to why this happened.
