My father stayed at Portofino for a night in Oct 2019 (the 7th or 8th) so I asked him if there was any construction at the time.
Here’s my dad’s report:
There was definitely construction.
The readiness of our room seemed delayed by it, the paint was not totally dry.
There was a room near by that seemed to be a staging area for construction, and there was some dust in our room.
There was no intrusive noise while we were there, but we were in the room from 4:30 till maybe 9:30 the next morning.
