As I have been using this hotel since 90’s, I can tell inside the room is a bit outdated. Still nice but they could update the bathroom. Apart from that, this is my go-to hotel when I visit Tokyo - business and pleasure. The location is very nice as it is right next to T-CAT (Haneda and Narita airport) and it is right above the metro station (Suitengu). I can hop on a train and go anywhere from there. It is also a good meeting place with friends, et al as we can go anywhere from there.
It is dead quiet in the rooms all day. I cannot even hear the traffic on the highways right next to the hotel.
The staff is awesome. They are very professional and always helpful. They go above and beyond expectations.
A bit pricey but nice things are. Try this hotel. I bet you will enjoy your stay there.
