Top Kastro Hotel Reviews

Sifnos House - Rooms & Spa

10/10 Excellent

"Great attention to detail and a lot of personalized customer service… Great location and comfortable accommodation"

Boufounis Studios

10/10 Excellent

"We had a wonderful time there, we stayed for a week and we had a wonderful partial view on the sea. Everything was clean at all times, the host was very friendly and welcoming. Near everything and easy to go anywhere on the island. This place is certainly one of the highlights of our trip. The bed was super comfortable, great shower, coffee every day. We felt blessed. Thank you for everything! "

Smaragdi Hotel

10/10 Excellent

"I really enjoyed my stay, the owner was so kind and friendly, the staff in the attached restaurant and around the property were friendly and helpful too. The room was beautiful, calm and sleek. The balcony had a view of sunset, and this was also the first Greek hotel I’ve stayed in that already had an iron in the room! "

Nival Boutique Hotel

10/10 Excellent

"What a gem of a hotel! My husband and I spent 3 nights here for our honeymoon and we felt so special, taken care of and content. The decor is boho chic, the rooms are perfect, the pool is clean with beautiful views and the food is AMAZING! After almost two weeks of greek food, we could not be happier to have the most delicious smashburger and gourmet fries (breakfast was good, but highly suggest eating lunch or dinner here too). Being a boutique hotel, it was quiet and personal. Each staff member was so friendly and kind!! We appreciated that they cared to know our names and get to know us. A huge thank you to Despina at the bar for remembering us and what we liked to order for lunch, as well as Georgia, who was SO enthusiastic when meeting us and serving us celebratory drinks for our honeymoon! The kindest women! We truly enjoyed the peace that this hotel brought us as well as the ease of exploring Sifnos (there is a bus stop you can walk to - 2 minutes down the road - and 10ish minute walk to to village of Apollonia)."

Stamna Sifnos, a member of Design Hotels

10/10 Excellent

"This new property on Sifnos is perfection. There really is no other word to describe it. Book the room with the private pool at the bottom of the property if you want your own pool and the most private of rooms with the best view on site. The staff are fantastic and so quick to respond to new glasses or ice being sent to the room. The daily breakfast by the pool was sensational. Order the freshly scrambled eggs. They melt in your mouth. The rooms design and furnishings are straight out of a design magazine. Well done. The location is perfect. A short walk to Apollonia town if you want to get dinner and a drink. And also reccomend getting a car as you’re only ten mins drive to most parts of the island. "
