Very difficult to find reasonably priced hotel room during the golden week holiday. Semi-double room of Diamond Hotel is JPY12000, which is considered as a good rate So booked two nights.
Hotel is in Hanzomon which is a relatively quiet area. Going to other areas such as Ginza, Tokyo Station, Nihonbashi, Ueno, Shinjuku, etc is easy and fast. Room is small, clean, efficient. No complaint
