Didn't hugely enjoy my stay here to be honest - the flat is considerably more run-down in reality than the photos suggest, and there really needs to be some repair/maintenance work before future guests are hosted. The self check-in could also have been smoother - I was able to get into the building using the keys provided, but then had to wait 20 minutes for Silvia to inform me which flat was actually hers as there are a few at this address.
There were tiny shards of glass (?) on my bed when I arrived, and the shower doors were broken, as is the kitchen tap. There was also a strong smell in the kitchen though I couldn't figure out what it was, and most annoyingly, there's an incredibly loud generator on the terrace that went off every 15 minutes or so. I asked Silvia for instructions on how to turn it off, and she promised to come over and do so but never did (I was staying for 3 nights). The noise actually woke me up in the night a few times.
Also not ideal for kids - there's an incredibly wobbly banister on the staircase that seems like it's one push from breaking, and the flat is up two very long and steep flights of steps.
All in all I think you can definitely find somewhere better to stay in Palermo.
