Loved Castello.
Staff were wonderful helpful and friendly. We were upgraded to a split level suite which we did not expect it was immaculate and we had a pool, sea view and a view of a beautiful church. Shower was fantastic and the bed huge and so comfy. Breakfast was nice with fresh orange and an omelette making station. We did not have dinner but wished we had tried one night. We had a couple of lunches which were fantastic.never had a problem getting a sunbed and the pool was lovely. We loved our stay at Castello and Sissi is a fantastic resort. Probably the nicest hotel we have stayed in all our travels around Greece! Hope to return one day

Staying in Sissi, Crete
The trip was excellent. The accommodation itself was perfect, as well as its location in relation to the local village. Sissi itself is a lovely place to visit , lots of nice bars and restaurants. The Castello Boutique Resort is a great place to relax and enjoy yourself.

Greek Holiday
My husband and myself had a lovely relaxing stay at the Costello Boutique, our room was very comfortable and clean and we received a bottle of water, a bottle of wine and a plate of fruit when we arrived. The dinning room was open until 10pm so we were able to enjoy a lovely meal when we arrived. Not much has changed in Sissi since we were last there 3 years ago so would go back for the hotel rather than Sissi itself which is a little run down
