Siracusa is beautiful and Maita's apartment is right in the middle of it all just a few steps (literally no more than 3 or 4) from the main Duomo Plazza, which must be one of the grandest we have seen in Europe. The apartment is clean and fresh and everything very well represented in the photos.
For us, the apartment was absolutely fine with two adults and 3 children, with 2 children in the upstairs double room ( with the ensuite, which they absolutely loved) and one child on the ground floor in the fold out bed. If however you were relying on the 6 persons to sleep, it certainly can be done, but it would be uncomfortable if you were not in the same family as there is no downstairs bathroom and the fold out bed pretty much takes up the living space when the bed is unfolded.
Other than that, the apartment was a delight and we would highly recommend.
