Actually, we were perfectly reachable.
My phone was unfortunately out of order but I gave you the number of my boyfriend mobile and we talked with you on the phone at around 7 pm the day of our arrival. The evening of our arrival, we also sent 4 sms to your friend (the one that hat welcomed us since you were not in Syracuse). She perfectly received them.
Anyway, as I said, nice appartment. We recommend it. And Syracuse is a lovely place.
