バイクでの1泊ツーリングで利用させていただきました。 【よかった点】 ・屋根付きの駐車場にバイクが停められたので夜中に天気が悪くなってもバイクの心配せずに済みました。 ・温泉があるので足を伸ばして入浴し、疲れを癒すことができたのはとてもありがたかったです。 【少し残念だった点】 ・温泉の湯温が少しぬるく、もう少し温かかったらもっと気持ちよかったと思います。 ・歩いて行ける距離にコンビニはないため、バイクや車で買い出しにいく必要があります。

２３時過ぎに大浴場へ行きました。床一面髪の毛等が落ちていたのを、宿泊客が掃除してました。ホテル側は張り紙等をし利用者に掃除をお願いする、利用者も後の人のことを考えてコロコロを使うなり髪の毛を捨てるなりしてほしい。

In our three hotel rooms, the piping at the bottom of the sinks drained into open drains, which caused the hotel rooms to smell pretty awful (like sewage). There was also mold in the bathroom and the air conditioner vents were covered with grime and dust. I don't recommend staying here - spend the extra money to stay at the Route Inn down the road from this hotel.

値段相応でしょうか。

本館の離れになるのですが、明らかに昔のラブホテルですかね。 部屋も清潔感は無く、何しろ温泉の浴槽の床がぬめぬめで、掃除している感じはない気がしました。 全般的に、とても不潔な感じが否めません。 唯一の利点は、バイクで行きましたので、屋根下駐車場に停められた点でしょうか。 ライダーで、あまり清潔感にこだわりの無い方であれば、お勧めできるかもです。 一般の方は、再考なさった方が宜しいかと思います。

部屋が二手に分かれていて、思ったよりも広くて快適だった。 駐車場はグリーンホテルと向かいのプラトンホテルの2つあり、空いてなければ向かいに停められるので助かった。 それと今回はチェックインが遅くなったのでプラトンホテルの方に泊まったが、チェックインはどちらのホテルでもプラトン側のようである。 サービスは良く、値段の割に広く快適な部屋であった。

非常に古く、ざ・ビジネスホテルではあるが、近隣にあるグループホテルの温泉にも無料で入れるため、温泉好きには良い。この値段で朝食もつくので、まあ、良いのではないでしょうか。

This is not the ritz, but it was definitely worth what we paid for it. It is pretty far from everything, the rooms are old and dirty, but the customer service was amazing!! I'd stay here again just because of the guy at the front desk. When we discovered a leak in our room, he moved us to another with no questions asked. Unfortunately, the room he moved us to smelled like something died in the drain, but we decided not to complain, which is on us. I am sure he would have taken care of us if we had.

値段成りですから安く泊まる分には問題はありません。一般的なホテルのサービスや設備を求めるならば、そちらにどうぞ。但し、提携？系列？の温泉施設が利用できるのは良かった。時間制限が無ければもっと良い。ホテルとは関係ありませんが近くの飲食店が軒並み休みだったのは参ったｗ
