We had a mixed experience when staying at the Airbnb.
First of all the Co-Host Claudia was great, very kind and quick at responding to any questions. She checked in on wether everything was working out and helped us with recommendations on what to see. The location of the accommodation was wonderful. It's one of the historic building in Ortigia, but has a lot of steep and narrow stairs, so I wouldn't recommend it if climbing stairs is physiologically difficult for you.
But there were some problems:
There was construction work in the apartment next doors, starting around 8-9 in the morning, which we weren't informed of. Also the apartment was not very clean, the floor was was sandy and there was hair from the previous guests in the sheets and the sofa. We also had to clean the chairs and the table on the terrace from bird shit.
The upstairs toilet had so low water pressure to flush, so we only used to downstairs bathroom.
We personally didn't find the bed very comfortable, the mattress seemed worn out and the pillow was uncomfortable, but that opinion might differ from person to person.
We enjoyed our stay in Ortigia none the less and since these are easy to fix issues I'm sure you can have a wonderful stay at the apartment.
Thank you Claudia :)
