We LOVED it here ! ( this review is long because we have so many nice things to say ! ) I researched a lot to find the perfect spot for our trip, at found it at Tinos, at Georg's house. Starting with the warm welcome -Jenni and Babis greeted us late at night at the port (we had our own car) and followed them up a winding road under a full moon to the house -magical. Even though the photos are very accurate, we still had a "wow!" moment when we walked in the house. Jenni explained everything, pointed out interesting things on the map, answered all questions.
The beds were comfortable, with new comforters. There were hotel style sheets and towels, a heated towel rack in the bathroom, an equipped kitchen with an espresso machine. A washing machine in the building, parking at the front.
The second night was chilly and the heat wasn't high enough for our taste but we were able to contact Georg in Sweden and he explained EXACTLY what we need to do to turn the thermostat up.
At night, it is VERY quiet and dark. You can see Mykonos and other islands nearby.
Georg was generously accommodating when there was a ferry strike and we were stranded for one more night on the island.
Jenni came down to the port as we were leaving to be sure we everything was okay and to see us off. Another nice touch!
There are two great restaurants nearby - one literally 30 seconds away by car ( it's sign is two sheep) and the other 2 minutes in the other direction. Both had great food, great prices, the waiters spoke Greek, English, French etc

Tinos itself is fantastic, it was exactly what we were looking for -quiet, safe, respectful, authentic. We were there in mid-May so before big tourist season. The port area was quiet during the week but on the weekend we saw the many restos and cafes start to fill up nicely. The port is spacious and quiet ( as opposed to Santorini that was crowded, chaotic, aggressive). Tinos has many small villages each with their own secret places worth exploring. Right behind the house was such a place with chapels, houses, alleys etc.
There are a few clean modern grocery stores, many art&jewelry shops, great bakeries, a specialty pastry shop, Halaris, that is well worth going to. Save time for Pyrgos, and the many beautiful beaches.
If you are planning a trip to Greece and are trying to decide which places to visit, I would STRONGLY suggest Tinos for families or people looking for a more quiet and authentic side of Greece. You definitely need a car, but there are places at the port to rent one.
I cannot recommend Tinos and Georgs house enough!
