Okura Act City Hotel Hamamatsu

Okura Act City Hotel Hamamatsu

8/10 Good
"I have stayed in this hotel many times over the last 25 years It’s still a lovely property and a nice place to stay, But unfortunately a number of its wonderful facilities are now no longer available. The Amazing 25 m lap pool is now closed and the superb cocktail bar with city views is also now closed. I am wondering if Okura maybe considering exiting this property ??? "
