I stayed at the InterContinental Strings three times recently, and every time was amazing. Once you reach the lobby on the 26th floor, the service and attention to detail was outstanding. I had two
different floor plans and, while I liked the larger room a bit better, even the slightly smaller (maybe just different) floor plan was very comfortable and accommodating.
You may be paying a bit of a premium to stay here, but it is a very worthwhile investment. And the close proximity to the Shinagawa train station was a nice added bonus. I will definitely stay here on my next visit to Tokyo. [Less]
