Just got back from a stay at the Hotel Nereo but was so disappointed that we weren't advised by Jet2 holidays of the building works that were going on.
They are still refurbishing the 10th floor so we had to endure constant noise from 8 in the morning until 8 at night. At one point there was debris falling onto our balcony, and they had to cordon off part of the sun terrace as people were getting hit by it.
Our bathroom was flooded from above, although when we informed reception they were quick to come and clean up. Other guests were saying that the noise could be heard on all floors.
I would be interested if anyone knows if a tour operator has to inform of building works and if it is worth writing a complaint.
