The 25th Aisna Biennial Conference will be held at the SDS of Foreign Languages and Literatures located at Via Orfanatrofio 49, Ragusa Ibla. Ibla is the historical section of Ragusa, so your first choice might be that of choosing a hotel or a B&B located in Ibla. In this case, you will be 5-10 minutes away from the conference venue.
Ragusa-Centro, though, is only 20 minutes away (on foot) from Ibla, or 5 minutes by cab. The cost of a cab will be € 2,50 only per person, for 4 people (i.e. € 10,00 for a regular 5 seat car).
