The communication was really easy directly via whatsapp and people of the agency were really reactive.
When we arrived, the flat was really great, huge, in the center of Syracuse, and the location in a small street. They forgot to mention that the flat is just above a restaurant, the 2 bedrooms have their windows on the restaurant so very noisy. Of course we could hear people from the outside, but also the big group inside : hands claping, ring when dishes are ready and even noises from the kitchen. That's too bad and it is not a detail and has to be mentionned in the ad which was not. If you are a young couple, going out, not bothered by the noise, go for it, but for a family like us with a 11 months baby or even young children, noise at evening until 1 am, not.
We told that to the agency and they were reactive because within the day, hopefully, one of their other apartment was free so we move in to another appartment which was half size of the first (65 m2 vs 120m2) but enough for us and in a very calm district, still in the center. But with no washing machine and no wifi.
Anyway it was much better, apart from the price which remains the same but with a smaller flat, with less equipments. Closer to the sea sure but prices are less on other platforms.
Just to tell the futur travellers : this flat has no kettle and toaster which are simple equipments and even more needed as a family :) But baby cot provided and high chair, good points :)
And they were helpful with local tips in the City, thanks.
At the end we are quite happy with our stay, but we need to be sincere on our experience to help future travellers. It's the motto of AIRBNB :)
