Checked into our room and there were screaming kids opposite. After a few mins I went to reception and asked to be moved, which we were, though the the front desk seemed hacked off about it.
In our second room there was a whining and barking dog opposite. I'm a dog person, but it was clearly in the room alone, it was off and on the whole 2 days we were there.
I could hear toilets flushing all night, a vaccum/suction sound, and one night I counted 14 times (couldn't sleep). I could also hear a guy snoring next door so, don't believe any claims their rooms are soundproofed; they're not.
So, all in all, noise was the main issue at this hotel and a lot of it impossible to ignore.
I refuse to let this stuff spoil a holiday, but it was there, triggering, despite a wonderful trip to Italy.
