We had a wonderful vacation.
Ioannis have meet us at the port and gave us a lift to the apartment. Then he prepared another surprise for us: a small bottle of local alcohol beverage Raki! In addition he gave us some local tips, including the bus schedule for the region. At total, the hospitality was just fantastic!
The apartment itself was exceptional, exactly like described, with additional cleaning during our stay there (less common practice on Airbnb).
The sea beaches is very close to the apartment, about 400 meter. The buses goes to the town of Tinos once in about two hours in the off-season (September) for the price of 1.60€, but you can take the taxi for 10€.
