Our stay at Calo's place was great. We booked just a couple of days beforehand and he was very accommodating, meeting us there and explaining how everything worked in the flat and where to find transport and facilities nearby. An easy walk from both the train station and bus station. Equally easy to get to the Archeological site by public bus.
The flat had everything we needed. We'd be happy to return there if we were in the area again. Highly recommended.
