The flat is very close to everything in Ortigia and is big and nicely furnished. However we had a few issues with our stay. The lack of windows that you can open in the flat meant that moisture from the bathroom after a shower went into the bedroom and made the bed and walls feel damp. The mattress definitely needs an upgrade, and something should be done so that the bedroom doesn't get so humid, as it's not pleasant to sleep in.
However, the biggest problem for us during our stay was mainly how noisy it was - the flat being on the ground floor of a fairly busy back street, with thin wooden doors and wood ceilings meant constant noise coming from upstairs (can hear people talk, baby cry etc very clearly and late into the night) and outside (you can clearly hear passerby's conversations and it sounds like they are in the next room, as well as scooters).
This was our last accommodation and unfortunately was our least favourite for the above reasons, we just couldn't get a good night's sleep due to the moisture and the noise going until very late at night.
Alessandro himself was very responsive and accommodating; since we were already in Ortigia he offered for us to leave our bags and come check in later, which was really appreciated. He also offered to get us a TV after we asked if there was one and gave us great straight forward direction for self check-in.
