Hôtel Mercure Paris Bercy Bibliothèque Reviews

I'm writing this review because my iPad Pro was shockingly stolen from my room, never to be found/returned since, which I think is outrageous for an expensive 4-star hotel (that did not take any responsibility for it). On the day we arrived, me and my friend used the ipad in the evening and I left it on the desk chair (the desk was full of our stuff). The next day, early morning we went downstairs to have breakfast and then spent the whole day out (queuing for the concert we were there for etc.) and coming back to the hotel after midnight, exhausted, when I did not think to check if my ipad was still on the chair (I didn't think things were at risk in a respectable hotel). The next day was check-out, so around 11 we cleared the room (was the ipad on the chair and I just missed it because the chair was a bit pushed under the desk? or did me and my friend not see it simply because it was not there? I wish I knew). We left the luggage at the reception and went to have lunch, because we had a train later in the afternoon. At lunch, when we had time to unwind, I realised I did not remember packing my ipad or seeing it since two days before; at that moment I thought I left it on the desk chair in the room and even though I was angry at myself for being scattered, I thought for sure the staff had found it and brought it at the reception. When we got back to the hotel and I asked the reception if they found my ipad (I thought it would be a simple convenience, because FOR SURE they would tell me they found it), to my shocked face they told me that no, the maid had not handed in anything from my room. I was stunned - I waited for the young woman at the front-desk to go check my room again, maybe it had slipped in a corner on the carpet and no one saw it - I realised chances were slim, but still I was in denial that it was stolen. She came back empty-handed and at that point I opened my suitcase (a huge one) in the middle of the reception, thinking that maybe I was mad and had packed it out of instinct, not remembering it. Of course that was not the case. I started a heated conversation with the receptionist (looking back on it, I was too mild, I should have screamed at them, but I am not a confrontational person - sometimes to my detriment). What was shocking to me was that even though I was in sheer distress and raised my voice, the man next to her - also part of staff and who seemed more senior than the receptionist - chose to ignore our conversation that was literally happening next to him and continued to hypnotise the paperwork in front of him, not looking at us once. That was a red flag as to the professionalism of the personnel (the other red flag being of course that one of them is a thief and no one cares). The receptionist said that the maid had gone home for the day (it was Saturday) and because I was leaving Paris that day, I should leave my contact with them and she would get back to me after talking to the maid the next day (she wrote dow
