I had a great stay in Palermo, the flat is as described and photos are accurate. I was a single, I think even for 2 people it would be spacious. A park with a walkway next to the water is about a 5-10 minute walk down the road, the train station is about 10-15 minutes, with shuttle buses going to the airport. There is a big supermarket around the corner so I was able to cook most nights saving a tonne of money. Heaps of coffee shops, bars and restaurants in the area. Check out the street food!
Antonella also let me know where things were in the area and was available on Whatsapp if I needed anything.
