Hotel Best Western di Lugano

This could have been a good hotel, albeit quite pricy, but somehow justifiable through its location. But unfortunately I had the WORST ever experience I ever had in any hotel, anywhere. On the good part: Good location in Paradiso, on the promenade, 15 min walk on the promenade to the center of Lugano. Nice lobby, good breakfast and friendly staff (at the breakfast, and partly at the reception). But the good stuff ended here. This stay was part of a multi-city trip with three stays and I simply forgot at check-in time that the booking was actually for lake side-view room. We arrived and completed check-in by 2:30. The lady at the front-desk told us the room is not ready and we need to wait till 3pm. I asked her kindly if she can check with the housekeeping if room is ready, being only 30 min left till 3pm, but she just told ”no, it's not”. Then I asked her to give us a lake or at least lake-side view, but she told that the hotel is fully booked and our room is with pool view. We didn't wanted to wait till the room is ready, so we just left the luggage and got to the city. We returned at the hotel late, by 9:30 - 10pm and when we got to the room (I think 315) we had the unpleasant surprise to see the ugly view from the balcony (construction site or quarry). In the bath the stopper was stuck and the sink quickly filled with dirty water. I called the reception to fix, the lady from check-in came but she told there's no-one in the hotel at this hour to fix, and she left. So I had to put my hands into the sink filled with dirty water and take off the stopper. Then we wanted to turn on the TV which didn't worked. I called the reception again, and someone came, took the remote to change its batteries, but the TV didn't started either. So he told the TV might be broken and they try to fix it the next day. I found finally that the TV was stopped actually from the hardware power button, because the remote power button actually didn't worked. All this added to my frustration, and I finally realized that I actually booked a room with lake-side view, which they didn't gave me. So I went to the reception, showed them the actual reservation confirmation and asked again for the room I paid for, which they told they cannot because everything is full. I asked to change my room the next day as booked, or I'll make an official complain to the Tourist Authority. Few minutes later I got a phone call from the reception, telling me there is a manager available, and if he can come to see the room and talk. I said of course. My mistake! At the door arrived the lady who checked me in, accompanied by a person, who stepped int the room and asked me what is the problem. I started to tell him we are booked for a side-lake view but we didn't it, but he interrupted me and started to raise his voice, telling why I keep complaining! What I don't like about the room? Isn't the furniture new and the walls newly painted? I told I never complained about what he says, I just want to get
