I really liked the stay at Colin's place! It felt as comfortable as being at home. Everything was clean, view from the windows was good, sound system and wifi speeds were also impressive, and surroundings were quiet.
Colin's assistant (Rosalba) helped us with any questions and was available via WhatsApp at any time.
There's a famous Santa Lucia hotel nearby, with great bar/gelateria to start your day. Cefalu famous beaches and multiple groceries are 10 minutes away by car.
A few tips:
1) car is almost mandatory - house is on a steep hill, and climbing there is difficult even after sunset. Also, getting to Cefalu center by foot is not a relaxing experience.
2) sound system is very nice - if you like music, you'll like staying here.
3) wifi connection was the best we've experienced on Sicily - fast and reliable.
4) don't forget to visit Cefalu after 8 pm - city really wakes up with multiple bars and restaurants
