The room didn't match the description on Expedia. The front desk clerk (which is a tiny desk on the stairwell landing between the first and second floors) explained that none of their rooms have televisions or a working safe. Their rooms don't include hand soap in the bathroom. You get to wash your hands with the tiny tube of shower gel they provide after using the toilet. Their jacuzzi was filled with dirt and leaves upon my arrival. One person told me that it hadn't been used since COVID. They did sort of clean it up and fill it with water, but I wasn't about to be the guinea pig for that. This place was probably quite nice 20 years ago, but it's best to avoid now until somebody remodels it.

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.

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.

Disliked: Cleanliness, property conditions & facilities, room comfort

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.

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!!!!!!!!!!!!
