Any thoughts reagarding on the park hotel tokyo? I see a king corner room at just under 30,000 JPY taxes in. Seems like an easy journey to Haneda (yamanote to keikyu line I believe) and it would save me 5000k JPY from The Strings.
The transfer from Yamanote line to the monorail at Hamamatsucho is very short and easy. However, the Park hotel is probably a 7-8 minute walk from the station. If you want a short walk from your hotel to Shinbashi station the Dai-ichi Hotel is closer. Possibly cheaper too. It's an older property, but decent.
