We stayed here for two nights but we will definitely come back at the end of our trip. We stayed at a 5 beds room and it was really clean. We didn't like the plastic on the mattress but we understand why they do that. The bathrooms have hot shower and were also perfectly clean. The staff was so helpful, they helped us with every question we had.
There were not so many guest but we liked that. Our room was at the first floor and you could hear the people speaking in the lobby, so maybe if they are fully booked, it could get a little bit loud, but didnt happen at our stay. They are situated in the centrum, so everything ( 7/11, food court, shopping center ) are close to them.
All in all a perfect stay for a few days in Bangkok.
