HOTEL SUI HAMAMATSU

10/10 Excellent
"Absolute great experience here, no complaints. Hotel isnt to far from the train station, and near a bunch of great restaurants that also stay open late. Complimentary beer hour at the bar for hotel guests always a win. Staff were fantastic they made checking in super easy and were incredibly nice. Lady that checked me in spoke great english and an absolute joy. Would definitely stay here again."
