The room and the whole hotel were very clean quiet and Ii liked the interior design. I enjoyed having the overhead shower and I was happy to find a blow dryer in my room as well. The wifi connection worked fine with my computer (but I experienced lags on my smart phone). The bed is quite high, which I personally like a lot as it is very comfortable to get up from them, but someone with young children may not feel at ease.
The location of the hotel is quite convenient - right at the city center, but I had troubles with getting there with my luggage (I went from Hisayaodori subway station), so please check the route or take a taxi if you plan to travel with heavyweight suitcases.
I think the price/location/quality/comfort ratio is quite excellent, so I can definitely reccomend this hotel for solo trips.
