We really enjoyed staying at svens apartment. The check in was super uncomplicated and the location was really nice for exploring palermo. Things I would have loved to know beforehand:
In order to get to the roof top balcony you can see on the pictures you need to go through a really tight staircase which means breakfast up there is rather complicated as carrying everything up their would be a bit of an act. Additionally, the kitchen countertops are veeery low, hence for tall people not ideal to cook there a lot. Other than that everything was as expected and we had a really nice time there :)
