The flat is very spacious and clean, is nicely decorated and has good amenities in the kitchen and bathrooms. We were able to check in and out very easily.
For light sleepers, this may not be the ideal flat for you however as it is quite noisy - not a problem for our group generally except a couple who find it harder to sleep with noise. One of the toilets blocked though Innocenzo was fine about it when we saw him- we think it might be a problem in Palermo generally so would advise never flushing paper.
The other slight confusion was that the bed/bedroom set up which was not as we had expected. There was enough space for us but not all were proper beds as we expected for a group of 10 - some were sofa and camp beds and one of the double beds was in the common area. Fine for our group as it was just a weekend but it was a little confusing so if this is something that affects you better to ask Innocenzo who I am sure would be happy to answer any questions.
Overall a decent stay for a weekend for a group of friends.
