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

A cut above the rest
Unfortunately too short a stay. Excellent staff/ service. From Eleni and Mora on check in to Apostolos on checkout. Great food as well as ambience.

Very Good8.0
Small, modern hotel in quiet village by the sea
Made to feel very welcome by excellent staff. Food at breakfast and dinner was a little limited but did include Greek cuisine and was delicious. Spa, gym and pool were quite small but adequate. Room and bathroom large, well maintained and clean. Would recommend for a quiet, relaxing holiday. Car hire essential to explore further afield.

Season End Break
Nice comfortable boutique hotel with very friendly staff who are only too eager to help. We stayed in a room overlooking the pool/bar and were at first apprehensive given its location and the potential disturbance from the evening entertainment. However the rooms were reasonably quiet and the entertainment pretty low key. The food was good with a reasonable choice but don't expect the same variety as that provided by other larger 5* hotels that have 100's of rooms as this is a boutique hotel. The only drawback for us was the wifi which, whilst we could connect, was so slow 3G on the phone was considerably faster. In conclusion would recommend to anyone if looking to stay in this area of Crete.
