10/10 Exceptional

This was my first trip, and I truly enjoyed everything—the room decoration, the bed, and the overall environment were excellent. The front desk team was amazing; whenever we needed anything or had a question, they responded very quickly. Thank you so much, Thailand, for a wonderful experience.

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.

8/10 Very good

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.

Sarah, 1-night trip

6/10 Good

Pretty good

It's a good location, but the air conditioner did not work very well and the TV was not operative. The refrigerator did not work either but they did exchange that for a working one when I brought it up. The bed is very firm but I feel like that's standard in Asia and I kind of like it. Clean and good location to see all the touristy spots.

NATHAN, 7-night trip

6/10 Good

Plus for Nice location but the rest was not What i expect. No cleaning in 4 nights even i asked for it several times. Really hard beds and the room is not the size Hotels.com tell. The jacuzzi on the top had just cold water and was not changed. Had no Tv , and was only cold water in the shower. Will not change This room for next holiday in Khao San

property did not provide a tv in my room as listed in the rooms discripetion and had torn bed sheets
alexander, 8-night trip

6/10 Good

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
Paul, 4-night trip

2/10 Poor

A/C did not work and they tried to charge me more instead of a discount
J E, 1-night trip

4/10 Fair

The hotel is cute. The location is not great for getting around outside of Khaosan. The hot tub (pool as they billed it) was suspect. The roof area was dirty until the evening. A light was out in the bathroom, and they did nothing about it. I asked about getting to the airport, and an employee said to come down and order one from the front desk. I did that, and when I checked out, they had not done it! I went out and got my own. I asked earlier for a place to have breakfast before leaving for the airport, and the staff member said, "I don't know. I don't stay here." Great! Not again. LOL!!!!!!!!!!!!

4/10 Fair

Cheap and loud

The only thing that was good was the price, and 5min walk to Khaosan Road. Staff had Poor english, almost not even simple hotellexpressions. The AC, was broken in our room. So we got a downgrade in roomtype. From Superior to Standard and not even a compensation. Not even cheaper price. We payed for superiorprice. The AC in new room was only on or off, so we had to shut it down the not freeze. Almost all hotels AC's was direct outside our room and sounded all night. Bed was poor. We could feel the hard bottom of bedframe. Bad condition in bathroom, and the red towels had blechstains and edges was ripped. And did not get a recipt, even that we specially asked for it when checking out. They didn't understand what we mean. The picture on Hotels.com look way more better then the real condition.
