Dear R.O.,
thank you for your prompt as well as unfair review: we were waiting for it indeed, as your attempt of having your holidays paied by our hotel failed. Unfortunately since TripAdvisor has become so popular we are not the first hotel threatened to receive a bad review if we don't pay this or that sum of money.
Let us only give our version of the story for the benefit of our future guests.
You came back to collect your luggage at about 4pm and mentioned to me (the receptionist, I'm not even similar to the lady serving breakfast that morning) that you had lost a necklace and that it could have been left into your room.
Since nobody, neither my boss, nor the maids, have left any necklace for me, something that they are used to do when guests forget their belongings in the room after check-out, I had to check the hotel system to verify who cleaned up your room that morning and it results that both our maids cleaned that room together (one of them has been working here since the hotel has opened and she found a lot of forgotten belongings, including pcs, Ipods, brand glasses, one of the first I-phone,...) . So I phoned to one of them and she confirmed me that they didn't find any necklace.
As you were not satisfied with the response, I let 2 of you enter the room, praying you not to touch or move anything since guests were supposed to check-in soon and maids at that time had already gone. The system shows we have been inside the room between 16:28 and 16:35 and I don't even need to say that I had to tide up the room by myself after your departure, since you walked everywhere, and moved the possible to search your necklace that, by the way at that point you were sure was left on the shelf in the bathroom.
I've been working in 3 to 5 stars hotels for years up to now and I cannot even say how many times I've heard this story about the forgotten necklace, but I didn't accept your requests of a refund. I instead propose you to check into the vacuum: small things could been aspirated indeed.
When you saw how seriously I was taking your matter, you decided that the necklace was not so important to check into a vacuum (still quite important to have a refund for it) and left.
Needless to say anything else I suppose.
