Overall the property is an average business hotel experience (from what I've heard, as this is the first I've stayed in). The hotel is good for solo/duo traveling especially as the rooms are not big (normal for Tokyo) but the staff were exceptionally helpful. One of the staff spoke perfect English however the staff that didn't really helped stuck themselves out there to help us when needed (i.e. getting a larger taxi for luggage to go to the airport).
There were some very glaring problems with the property as we stayed up in the 9th floor and the doors may as well not be there from a soundproofing point of view. We would routinely hear people walking/talking/generally making noise outside of the room at all evening times.
Well worth staying at in order to get an easy taxi/transport link to Haneda.
