I would NOT recommend this space for groups - see below for more detail.
The space itself is very nice (although it wasn’t particularly well decorated and has the very bare minimum in terms of furniture and amenities) and the location is incredible - right in the heart of Palermo.
That said, in order to get into the building and subsequently the unit, you need two different keys. The problem though is that you need the same keys to leave the unit and the building - therefore, if someone has takes the keys with them, everyone else is trapped in the unit! It is both very inconvenient and in some cases quite dangerous. We asked about getting a second set (which would solve all of the issues) but the landlord said there was only one set and that we would have to make due. They have a safety deposit box out front which would be helpful if you didn’t require the keys to leave the unit - overall, the unit is nice and well located, but is incredibly inconvenient to stay with a group.
