We had a great at Claudia's place. It's perfectly located on the antique Ortigia island, sea side is just across the corner, 1 min walk. The apartment itself is small but looks spacious enough, all necessities are there. Especially, we appreciated a coffee machine and coffee capsules provided.
Although it's quite cold inside (old historical building with 1m wall thickness), air conditioners helps to feel comfortable. The only thing you need to get used to is weak water flow and thus it's almost impossible to flush shower/tap/toilet simultaneously, but such water issues are probably a general issue for such an antique island...
To summarize, Claudia is a great host, very responsive and pleasant person. Her place is definitely the value for money - absolutely recommend.
