Do you know these things where everything seems fine and yet there is something wrong? Our experience with Hotel Sempione was exactly like that. It is hard to pinpoint what specific things were wrong with the room, as everything seemed fine and nice on paper. Yet, we spent 3 nights at the Hotel and slept a total of around 5 hours. Not a lot for three days, but that can happen.
It was the small things, the pillows were very hard and big so the neck hurt, the bed was really hard so even my hip slept when lying on the side, and it was very loud at night from inside the Hotel and outside as well, plus we couldnt make the climate control work in the room which made it a quite hot place to sleep or wait till morning in our case. All small things that one can experience at a hotel, and yet annoying but what can you do.
To be fair the hotel had a quite nice location fairly central so they got that going for them, so far so good.
The thing we were least fond about were not the fact that they charged some tax at checkout though we paid already, nor that they were very rude at several interactions.
However they insisted that we handed in the room key when we left, and despite a do not disturb sign they entered our room every time we left to go out. We know that as a fact because we made small traps. When confronting the reception we were told we lied and were therefore yelled at. This was not very pleasant nor nice to know someone sneaked around in the room. Very unsetteling.
