We did not not meet Rosa but her friend met us to welcome us into the apt. He explained everything very well and even pointed out some interesting places on the map for us.
There was a nice bottle of wine to welcome us and the apartment was located within walking distance to Ortigia, which was amazing. We had one of the best evenings, walking around Ortigia, highly recommended.

Our two big frustrations with the place were (which almost negated the positive aspects of the place):
1. Elevator did not work the entire duration of our stay. We had to carry two heavy suitcases down three flights of stairs and also climb up every evening when we returned home tired after exploring all day. I feel the host could have communicated and warned us that the mechanic was in the process of fixing the elevator
2. When we checked out, we were told to leave the keys in the apt. However, you need the keys to get out of the building! We had to wait almost 30 mins for another resident to pass by and let us out of the building since the keys were left in the apartment. I feel maybe the host could have helped coordinate our check out so as to be there to pick up keys from us or let us out of the building.

Overall, would recommend the place if you've cleared the above points with the host. The apt itself was perfect, very clean and spacious and great views of the island.
