Adriana's place is located very, very close to the beach. It's very accessible from the train station and is smack in the middle of the town. Can't beat this location.
I stayed here for 5 days and I wish I could've stayed here for longer. The place is huge and very cozy and comfortable. She was an excellent host and provided with great recommendations and amenities.
If you're visiting Cefalù and want a chill vibe, spend as much time here as you can!
