We had wonderful 6 days in brand new clean house, with exceptional sea view. Our goal was escape from big city where we live, so we were looking for a house in a middle of nowhere. And we found it:) October is already a low season, so there were almost no one around, no tavernas opened (so you need to buy all the food with you) and a wonderful beach in 10 minutes walk.
Usually, this house needs a car, but we were able to had a great time without it.
Maria and Yannis (Antonis parents) are wonderful hosts and took us to supermarket and even gave us a tour around Tinos.
The only issue I experienced is that there is a lot of construction going on around the house as tourism is growing and becoming more popular on Tinos and everyone is trying to build their own houses in a nice places to rent or live. So construction was going on the weekend as well, to make sure they are finished before next summer. So on a high season this should not worry you, but on a low season I would ask whether it will be a lot of construction around just in case you want 100% peace.
I highly recommend this house.
