We had a sublime 10 day stay at Petrafos - couldn’t recommend it more! Petros & Petrina are spectacular hosts.
The villa was extremely clean, authentic and the perfect space for two - with out-of-this-world views!
You will need a car though as the villages of Tinos are a must-visit, but the local beach (which was lovely with many good bars) is a 20min walk from the villa. The local tavernas (try Veranda) are great but there are facilities for basic cooking too for cosy nights in on the terrace.
