So firstly know that Casteldaccia, nothing much is happening. Come with a car to be able to appreciate what is around. The apartment was very sunny & cheerful and a good price The owner is in Vancouver BC& has strick rules on not to be bothered( our experience). When we asked questions, her reply was: this is not a Hotel. Allasandra her manager, not speaking English was sweet. Know that a spiral staircase winds its way to the 3rd floor. It is very well situated, close to the only market & piazza with only old men. People in Casteldeccia, are very helpful and do not speak English.
The train is about 25 " minutes going down & more going up, do not walk around at night in that area.
The one bus stop is not identified, neither ate the streets mostly.
