The hotel's facade was being renovated while I was staying there. I woke up to construction workers walking outside my (third floor) window on scaffolding, which was an unpleasant surprise. I hope that the hotel staff would have informed me about the renovation beforehand, because I was traveling for business and working from my hotel room.
The renovation made working almost impossible: noise, people working right outside my window on scaffolding, and being forced to have curtains closed from 8 am onward, so no daylight entered the room.
