We just had the most amazing stay here. The apartment is in a brilliant place with fabulous views over the rooftops. Everything was very clean, the kitchenette had all we needed and our favourite thing was to sit on the roof at night gazing at the stars.
A few things that might be useful to note : access is via stairs only and it is a climb (we were glad to work off all the cannoli but it could be hard going for some); while the space could sleep up to five people it is open plan and so most ideal (we felt) for a couple.
We never met Michi in person but she was fabulous to deal with, lots of communication and very accommodating when our flight was suddenly delayed by 10 hours. We would recommend her place and palermo to anyone and hope to return.
