This place is really nice ! If you travel with a group or if you are willing to meet new people I am sure you can have good times at bar downstair.
The room looks really typical with the sliding window (however do not open them, there is nothing interesting behind them :-D)
It might be not really central and you have to walk 10 good minutes to reach the subway.
The main problem though is the noise. It can be really loud and I think they are aware of that because they are offering earplugs.
I also really like the free sake to meet the team.
I recommend this place.
