Wow, what an amazing experience - Franco must be the kindest, most accommodating host I've ever had on Airbnb. He really goes the extra mile and beyond to make sure that you have a great stay - I had to cut mine short because of Covid and he couldn't've been more helpful. The flat's lush too, really roomy and comfy, up-to-date, atmospheric and sparkling clean, and lots of goodies provided too. All amenities there, including a washing machine and good wifi (there are some corners where the signal can get a bit weak, I think because the walls are quite thick). It's just behind Castello Ursino so really near the centre of this wonderful city.
The only thing I would say is that it's on quite a noisy corner with street traffic. It's fine with the windows closed as the quality of the double-glazing is good, but it's something to be aware of. There's aircon in the sitting room but not the bedrooms (at least not in the one I slept in). Anyway I loved this place and was so sad to have to leave early. I'll definitely keep this place at the top of my list when I come back.
