i had a very last minute trip and had to stay in akasaka/roppongi.
it was more spacious than akasako yoko hotel (where i moved from)
i booked a single but was given double somehow.
the room is using the old style key but not a big problem
i had a package delivered to the hotel, however they had hard time finding it
near the convenient stores, about 7 min walk to akasaka and 7 min walk to roppongi
