Excellent food on site
Benjamin, 1-night trip

10/10 Exceptional

A plethora of breakfast options were offered every morning. In the evening, snacks and drinks were provided for a few hours in the lounge. A person could easily spend the whole day here. You'll be fed, there's a pool and spring, a shop on the first floor, free drinks. This place is well worth your $$. We felt very well taken care of. We are likely coming back on our next trip to Japan.

A spa hotel 30 min away from the center

This is a spa hotel with mineral baths, excellent food and drinks. It's a bit far from the center of Hamamatsu city (30 min by taxi), but it worth the drive. Service is excellent. Executive lounge with free drinks on the top floor is supper nice (you need to stay in the executive room to have access). The only minor issue - no aircon in the corridors of the top floors. The aircon in the room worked perfectly.

The hotel is a bit old and could probably use a remodel. However the hotel is clean, has a nice onsen, and the customer service was very good. My kids also enjoyed the outdoor pool the resort has. I would stay again if I visited Hamamatsu again.

Check-in was easy and staff was very friendly - was able to add another room for the night for our teen kids. There was a function on in one restaurant, and according to staff, all other restaurants were unavailable. There was very little within walking distance for us to eat. Staff offered to call a cab, but cab company had a long wait time. Breakfast buffet was very good with many options.

They server breakfast and lunch with no food options in-between. nothing at all the closest place to get food is a 7-11 that is quite a walk away. the pool is nice but shuts down frequently for no reason. they havea ping pong room but again it is only open fro a few hours after 3pm. therre is a lot of time with nothing do do with your kids which is not great.

外国人観光客で溢れててうるさかった。 バイキングのクオリティと値段が釣り合ってない。外国人に合わせすぎてる。 スタッフのクオリティは低い。

息子の誕生日で利用しました。 事前に誕生日サプライズでフラワーアレンジメントが無料で出来るとの事でお願いしましたが、結果何もありませんでした。 また持ち込みでケーキを持ってきたので 部屋にお皿とフォークをお願いしましたが 人手不足と言う理由でだいぶ待たされました。 満足度はやや低めでした。
直也, 1-night trip

10/10 Exceptional

朝晩のビュッフェはたしかに混みますが、追加の食事会場は十分に広く、メニューにも工夫が凝らされていて美味しかったです。　 食事時、チェックアウトのタイミングでエレベーターが混むのは仕方ないかと。 露天風呂とお風呂上がりのドリンクサービスは満足できますし、宿泊した部屋は綺麗に清掃されていたので、ほぼ不満点はありません。 ちいさい子ども連れのファミリー旅行として一泊するに申し分ありませんでした。

チェックインがとても混んでいましたが、ロビーのサービスが充実しているので問題なく待っていられました。 その他についてはとても満足です。 唯一気になったのは、部屋にドライヤーがなかったことくらいかな。

何年か前に行った記憶は良かったので、また利用しましたが、口コミの通りエレベーターがなかなか来ないのと朝食も席が足りないのか残念でした。あと確認不足でしたが、布団を敷くのがセルフだったのが残念。 でも朝食はバリエーション豊かで、プールも気持ち良かったので機会あれば利用したいです。

小学生連れの家族旅行：ラウンジでまったり過ごせます

駐車場のスペースは十分にありました。 チェックインは客室数が多いためか、混雑していました。ラウンジで飲み物とスナックがいただけるので、待つことは苦になりませんでした。 整理券の順番が来てからも、チェックインカウンターの前で手続き待ちとなりました。さらに客室に行くためのエレベーターが行列でした。 客室は清潔で広々として快適でした。アレルギーのような症状が出てしまったので、子どもがはしゃいで細かい埃が舞ってしまったのかもしれません。 浴場も満足いくものでした。サウナもありました。夕食のタイミングで行くと比較的空いていると思います。 プールは怪我をしていたため利用できなかったのですが、とても暑い晴れの日だったため、プールでも快適に過ごせるのではないかと思います。 夜はプールサイドで手持ち花火をすることができました。火消し用のバケツが置いてありました。包装袋をバケツに捨てて行った方もいたので、マナーを守って使うと良いと思います。 ライターはフロントで借りることはできましたが、火種のキャンドルがあったほうが良いです。売店で花火とキャンドルが購入できました。可能であれば、チャッカマンを持って行ったほうが良いと思います。 夜もラウンジが開放され、スナックや飲み物、もちろんアルコールも楽しむことができました。ウナギボーンが美味しかったです。 チェックアウトはカードを返却ボックスに入れるだけで済みますのでスムーズでした。
