I stayed at this hotel for three nights at the end of September and was blown away by the beautiful surroundings. The pool is a tranquil escape where you can take a dip and soak up the sun with the smell of olive trees and lavender in the air. The staff were so friendly and helpful. Me and my boyfriend have said we would definitely go back and recommend to family and friends. The al la carte menu had some great dishes; the happy hour was great and the view from our balcony was beautiful. The hotel is a short walk from bars and restaurants in Lassi and evener shorter walk to a beach. I had a wonderful stay.

The hotel was beautiful, although I actually stayed in what was once Silo apartments at the back of the hotel, which was not as good as the main part of the hotel.My room was very nice, but it could have done with a few extra comforts. There was absolutely nothing in the room with any information on it, like how to call reception or even how to dial out. No information on any local places of interest. A simple thing, no do not disturb sign for the door, so consequently housekeeping were forever opening the door to come in when I wasn’t ready. Housekeeping came in every day but was very hit and miss. Sometimes the towels would be changed, sometimes not. Sometimes the bins would be emptied, sometimes not. The sink was not cleaned for several days in a row. The balcony was messy and the table was never cleaned. It was €3 for a pool towel which I was told I could exchange every three days. What they did not say was that I would have to pay €3 every time I did that. The pool bar was very nice, and what little food I had there was good, however, you could not buy a cocktail there. I wanted to buy a sandwich and a drink there one day to take to my room, I was told it would cost me €5 extra for room service, even if I took it there myself and brought the plate back afterwards. So although I enjoyed my stay, there is room for improvement, considering the cost of the accommodation.
