Love Hotel Tamaike/Akasaka
Stickman,My favorite in that area is Hotel Chanty, address Akasaka 2-16-15. Basically cross over the major road from the front of the ANA Hotel, choose little lanes heading in a straight ahead-to right direction towards the TBS building, but you don't go that far. The hotel looks like a chateau so you can't miss it once you find it. It has interesting rooms (eg a large glass window from the bedroom into the bathroom) , and is relatively cheap. About 4-5 minutes from the ANA hotel. Lube
