　とても良かった。10月初めにホットタブ付きの部屋を2泊10万円で予約。ホテルコム経由でどんな部屋になるか不安だったが、部屋はビーチへ行く歩道に面していたものの満足できた。殆どの部屋は宿泊者が横を通り抜けて行く作り。プライベートプール付きだと他の部屋からほぼ丸見え。その点8号室のホットタブは比較的プライバシーが保たれていたのが高評価につながった。 　また、夕陽とともにホテルの売りであるインフィニティプールは時間帯によっては独占状態でまったりできる。 　朝食は1人10ユーロとリーズナブル。部屋は清潔で掃除も完璧だった。否定的なコメントが散見されたが、部屋によって満足感は変わるのだろう。朝食を運んでくれるスタッフも感じが良く、素晴らしい一日を始めるにはもってこいのホテルだった。

眺望は良いが、設備と対応が価格に見合いません

結論 景色は素晴らしい一方で、隣室とは実質ドア一枚で、襖一枚を隔てたように音が筒抜けでした。 深夜0時以降も話し声・ドライヤー音・荷物を片付ける音が続き、眠れませんでした。加えて、寒さ対策・清掃・連絡対応にも改善の余地を感じました。1泊7万円という価格に見合う満足は得られませんでした。 良かった点 眺望：街の雰囲気と景色がとても良く、散策を楽しめました。 気になった点 防音／構造：隣室とは実質ドア一枚で、襖一枚を隔てたように音が筒抜けでした。 深夜0時を過ぎても会話・ドライヤー・荷物の物音が続き、眠れませんでした。 水回り／温度：プールの水温が低く長時間入っていられませんでした。シャワーも十分に温まりませんでした。 設備：全身鏡がなく、服装チェックがしづらかったです。 清掃：ミニバーのコーヒーマシンに水が入れっぱなしでぬめりがあり、衛生面が気になりました。 連絡対応：客室にティーバッグはありましたが、湯沸かし器の貸出可否を問い合わせても返信がありませんでした。 向く人／向かない人 向く：眺望を重視し、外で過ごす時間が長い方。 向かない：夜間の静けさや館内での快適性を重視される方。 総評 景色以外は期待に届かず、価格帯を考えるとビジネスホテル以下という印象でした。再訪はいたしません。 Stunning views and pleasant city walks, but the stay lacked value for ¥70,000 per night. Soundproofing was extremely poor—rooms felt separated by a single door, and noise carried as if through a paper-thin partition. After midnight, conversations, hair-dryer noise, and luggage handling continued, disrupting sleep. Pool water was too cold to stay in, and the shower never got truly warm. No full-length mirror, making outfit checks difficult. The in-room coffee machine had stagnant water and felt slimy, raising hygiene concerns. Tea bags were provided, but our inquiry about borrowing a kettle went unanswered. Overall, aside from the view, the experience felt below business-hotel standards. Best for view-seekers who spend most time outside; not for those who need quiet nights or indoor comfort.

This is a great place that is quiet and no kids. You do have to climb stairs to get to or go from the hotel but the perfect place to watch the sunset night. People come from the island to where the hotel is to watch the sunsets. The staff was amazing and very helpful. One of the better places we have stayed

Had an amazing experience with the hotel overall , I loved how it was in the quieter part of oía and felt more peaceful. The staff and service were amazing and rooms were comfortable and clean. The breakfast here was so good i highly recommended to purchase. Just be prepared for cliffs and steps because they are all over the island. But we would stay here again for sure.

Santorini is absolutely beautiful. Old Castle is an affordable option and was just as described. We loved and used the outdoor pool/jacuzzi that was part of our room. Additionally, the hotel had a pool where we spent one day relaxing. The hotel’s location on the caldera is breath-taking and you can watch the sunset from your room/pool area. However, that means you need to walk a bit more to access the hotel - not a big deal if you are young, but we watched some middle-aged/older couples struggle with the extra steps to the hotel.

Awesome stay and an amazing place to watch the sunset. We stayed in a suite with a hot tub overlooking the water, which was wonderful. Surprisingly quiet at night given how close all the hotels are to one another. The front desk staff (Thanos) was so welcoming and lovely and even let us drop our bags off early in the day. Only thing that bothered us is that the air conditioning did not seem to bring the temp in the room to a comfortable level. It was a bit hot and stuffy

Location and view of the sunset are spectacular. However we booked the honeymoon suite room and upon entering, the room is nothing like the photos that’s presented online. Every room you see on the website all have a view of the sunset and a jacuzzi. Wish we didn’t spend the extra price for a room with small windows looking at the ocean. Would recommend to stay here but don’t spend a heavy price on rooms.
