I highly recommend Jean's house for both long or short term stays.
Jean is an excellent host who has put great attention into the design and furnishing of the space. Sharp knifes in the kitchen and soft pillows on the bed are my two key indicators for a professionally curated rental; my expectations were exceeded!
The rental is a triplex which provides the sense of depth and privacy. There are two separate outdoor spaces, one ideal for morning coffee and another for an evening drink that faces west towards the sunset. If you plan to set up an office, there is a good desk and reliably fast internet.
Palermo is arguably the most walkable area of the city and Jean's house is surrounded by a variety of excellent restaurants. Street noise is non-existent from the house, yet, one can walk a short distance to the heart of the party. Palermo is also a very secure area.
