We stayed at this hotel for two days while visiting Venice.There are a couple of severe issues which made our stay here very unpleasant: - For the start, we have been announced that the room price we negotiated with [...] is not correct and in fact we need to pay more (30% more per night which). We were astonished but what could we do vis-a-vis to the receptionist's (a Chinese immigrant), "take it or leave it" attitude? He lied that he notified [...] which will contact us. At that moment I didn't know the truth but after arriving home, I checked with [...] and of course all this proved to be a lie. Moreover, the continental breakfast was supposed to be included in the price I negotiated with [...] initially. According to the same Chinese receptionist, this wasn't true anymore so we had to pay extra for this too. - The breakfast was also substandard and just to give an example, although we just asked for coffee, we have been served cold coffee, probably prepared long before our order for some other clients which didn't use it. - Another very unpleasant experience was due to room HVAC "defective" unit. We stayed at third floor (the last) and the hottest. We thought that the HVAC unit was defective but in reality, deliberately we haven't been given the remote control of the said device. Initially, we didn't know that this unit is operated via a remote control so we asked (the same Chinese receptionist) to have it fixed. Only then, after one sleepless night, we have been handed the remote which was kept at reception and not in the room so I can decide whether to use it or not.In our opinion, all these issues were well "engineered" this way so the hotel makes undeserved profit. Although we paid more, we received the worst hotel service we ever had around the world I traveled so far.If the hotel management's strategy is to use Chinese immigrants as receptionists so they can "fight" for maximum profit actually works, the same management appears not to realize that the bad reputation they built in this way will fall back on their business and drive it under, which I surely hope it will happen.At the end, after we realized this entire diabolic scenario, I told him that I will make a complaint at [...] and at Trip Adviser. He didn't appear to be surprised. I wonder why!
