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.

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

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

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.

Based on the price I really wasn’t expecting much but I was pleasantly surprised! It’s in a nice quiet area right by the river, five minute walk away from Khao San Road. The staff was friendly and helpful, the wifi was good and the water pressure in the shower was good. The room and lobby was nice and clean, I didn’t see any bugs anywhere and there was no unpleasant smell that I’ve experienced in many other hotels. Overall great value for the price and I will definitely stay here again.

a somewhat dark and small but comfortable room
I moved to this hotel from a bigger one nearby that did not have room for me for the last three days of my stay in Bangkok. I had the mid-range room - which was very small - a large mattress on a slightly-raised wooden platform, a bench on which two people could sit side by side, and a lttte bit of floor (and a closet and mini-bar fridge). Bathroom was very small - no one over the age of about 6 could sit straigh forward on the toilet.. Water pressure was low. No hot water in sink (not a failure, just not provided at all - only one tap.) But the bed was comfortable and the room was quiet. Staff were helpful and friendly. So if you just want a place to put your bags down and sleep, this can do. It feels safe and it is in the Khao San neighbourhood full of backpackers and the hostels and small restaurants (lots on the sidestreets) that serve them and the locals. An agreeable area to stroll in, again safe and friendly. (And if you want a "Jack Armani" suit, you can get one made around the corner from this hotel!) If you need to work or read seriously, this is not the place for you, unless you can read or work in bed. The bench is not comfortable after an hour or so, though it's padded (as am I). There is not enough light to read a book. If you are reading a phone or computer or e-reader, no problem. I did some work one afternoon in the small restaurant on the ground floor of the hotel - part of the lobby of the building. That would not do at a meal time.

Good Value
Good value hotel, with great location. Room had all the amenities we needed with a pretty modern decor. Service was awesome. We were disappointed to know the upstairs jacuzzi didn’t have any water in it throughout our stay. Also, on our last day the sheet accidently popped off revealing large mattress stains which terrified us a little.

Super cheap place which is great. But there's reasons it's so cheap. Hotel staff weren't overly friendly or helpful. Room was extremely small, just enough space for the bed. But if it's just for 1 night and you're wanting to save money it's fine. If you're sensitive to traffic noise it was very audible from our room.

Great value, good location and clean
Great value. Ideal location walking distance to Khao San Road, water ferry and Grand Palace. Lots of shops, bars and eateries nearby along with convenience store etc. Room was small but clean and everything I needed was there. Lift access from third floor upwards only so be prepared to walk up stairs. Restaurant in the lobby area serving breakfast and food throughout the day. Would definitely stay again. A good value base to explore Bangkok and felt safe for lone travellers.
