"Good value for money with an excellent onsen. Rooms are a good size and comfortable. The dinner and breakfast buffet is good value and excellent. Front desk staff speak English. Hotel is near Lake Hamana and is quite far from central Hamamatsu. Not many restaurants or cafes within walking distance. Car or taxi is required for exploring the area."

10/10 Excellent

"Another great Hotel in Japan I love it"

Dormy Inn EXPRESS Toyohashi Hot Spring

10/10 Excellent

"If you are staying in Toyohashi, this motel is great. The rooms were a nice size and clean. The only issue I had was with the pillows...so hard. Breakfast was great! Staff was amazing!"

EN HOTEL Hamamatsu

8/10 Good

"Overall the stay was great. I just wish there were more power outlets in the room. The one by the door was too loose and couldn't be used properly. There was one power strip on the wall but that was it The one thing we didn't like was the smoking room in one corner of the main lobby. Even though it has a door isolating it, the smell of cigarette was still strong around the lobby and reception area."
