I was there in the mid of February so at nighttime it was still a bit cold to state at the house without heating system, but there was an electric heating stuff which I found only on the last evening :)
The remaining was pretty fine, no surprises or problems. The host Anastasia is very very nice and supportive girl. Once I’ll be in Palermo I will stay at her place again as it is good value for money. Best wishes, cheers!
