The best thing about Marco's place was that Marco was a great host. He provided us with very good recommendations for places to go to eat, see, swim etc. He was also always on hand if we had a question about anything.
The bikes were also great. It's about a 10min walk to Ortigia from the apartment, but this reduces significantly with the bikes. The bikes are also generally great for getting about Siracusa.
We were able to park right outside the apartment which was a bonus.
Apartment is quite small but very well equipped.
