I booked that hotel, because it is very convenient to go there from Suvarnabhumi Airport. The location is only a 1-2 minute walk from the BTS Skytrain station Nana. During night, there are a few bars around, that can be quite noisy. I got a room on the sixth floor, so i didn't hear too much of it, but can imagine it can be quite loud in the lower floors.
Upon check-in, you have to pay 500 THB as a deposit. The room was very clean, nice shower and a comfortable bed. I requested for a late checkout, but unfortunately wasn't possible because of being booked out. I left my luggage at the lobby and picked it up later for my flight.
