I recommend staying at Zacharias very highly. If you are looking for a quiet, comfortable base in which to explore the island this is the place for you. Mirsini is centrally located with good road links to the whole island. For the adventurous type who wants to explore all the villages, hidden beaches, man made and natural geological sites as well as many of Tinos' other intriguing corners, this couldn't be more suitable.
After a long day exploring or lying on the beach it was always a comfort going back to rest at our mountain perch spending the last moments of the day watching the clouds swirl through the onlooking valley. We were fortunate to come when the moon was entering its full phase so we enjoyed special moonlit moments.
