I unfortunately have to conclude that one aspect of the apartment makes it not a Plus apartment in my view (I was in apartment 2B). The floors are stone and wood. Which all looks very nice. Only thing is that the apartment above has the same finish and does not have sound proofing for the chairs. Which results in the worst noise disturbance from neighbours I have had in any AirBnB or hotel for that matter. They should really fix that.
I was welcomed by the mother of the host, which was fine. Language was a barrier though. She didn't speak English and only limited German. Ended up in a different apartment than apparently booked (she wasn't sure), but could stay in the apartment (which had a balcony and the actual one I booked apparently did not). So be aware there are multiple apartments and reviews may be combined over all of them.
Interior of the apartment is all very nice. Location is also idillic in a small Italian mountain town.
Would only go again if they fix the sound issue.
