The building is lovely, the location is perfect, the room is huge, the views are to die for and Marisa is an angel.
I would absolutely recommend staying at Pablo's place.
I spent far too much time sitting on the balcony gazing at the view but it is mesmerizing, especially at dawn. And if you pay attention you may even see some cute little bats swooping about at dusk.
If you love swimming then you have come to the right place, I found three free swimming platforms on the island, the closest of which was less than 5 mins walk away. I don't know if they are open all year round but they were open at the end of September and the water was still blissfully warm.
I borrowed one of Pablo's bicycles and rode along the 'pista ciclable' which starts beside the Monument to Africa. It's around 7kms if you go right to the end and the views are lovely - there is no shade though so avoid the middle of the day. Take your swimming gear because there are two more swimming platforms along the path.
And if you are looking for an interesting non-touristy day trip, search Airbnb Experiences for 'a taste of Sicily at our farm', it was a really great experience – and if you are there on Sunday morning then you may enjoy the flea market at the Piazza Santa Lucia.
Thanks Marisa, you made my stay in Ortigia really special.
