I published a big review of the Arts today, based on a stay at the end of June - https://www.headforpoints.com/2024/0...rts-barcelona/

It's got details of how the renovation will be done. Basically, room count is now 250 vs the previous 450. All rooms on one side are closed due to scaffolding, and three complete floors at a time are being taken out of action - the one being worked one and the one above and below to control noise.

This is actually a positive (until they start on the public areas and pools in 25/26) as the place is relatively empty. We had the adult pool literally to ourselves for the two days we were there. No problem with breakfast tables outside at peak times etc.
