Central hotel, near the famous Khao San road. A little bit tricky to get to if you’re travelling by car/taxi as there was no designated drop off/pick up point. Staff were lovely. Room and, overall, the property was stylish. It has the basic amenities for a one night stay.

Great location! Easy to walk to many landmarks and lots of good food around. The room wasn’t as clean as I would have expected when I checked in, but I told you staff and they remedied this right away! Unfortunately, the hot tub on the roof did not look like it had been cleaned or used in a long time, which was disappointing, but overall it was good value for solo traveler.

I so wanted to give a better review. Staff are so friendly and helpful. This usually makes up for a lot. I was sick when there so this was extra special for me. But when the electricity stopped working and they had to move me to another hotel they booked randomly (oh so bad) and no refund this was bad. Back to my stay in the diamond hotel. I try to ignore the fact that this building continually moves. Like earthquake wobbles. Very scary and often. Woke me up sometimes. They said ‘it’s ok’ mmmm
