Yannis, the host, is a lovely artist, who lives right next door and has his studio where he creates things on the same premises. He helped me guide the taxi from the ferry port to his house and was always accessible via text, whatsapp or phone call. He answered all questions I had very swiftly, and particularly helped me at the end of my stay - when I loved it so much that I rescheduled my flights but had to find another air BnB - recommending other nice places, calling friends to find accommodation, keeping me from staying in an extremely ugly hotel, and finally arranging for my luggage to magically appear where I needed it.
Location: The apartment is situated around 10 minutes drive from Tinos town. Busses run every 2 hours from a stop around 5 minutes away from 8.20 to 22.20. The other hours are served by a bus stop at the other end of the beach in Agios Ioannis Porto, which is about 15 minutes walk from the apartment. Having a scooter or car is useful, while not strictly necessary.
The house: is absolutely lovely. It is freshly renovated, all painted in white - you would see the dirt very clearly if there were any, but it was absolutely spotless. The beds are very comfortable, it is very quiet at night, so you are down for a good night's sleep. The best thing is its closeness to the sea. It is literally a stone's throw away. From the terrace you have the most beautiful view of the sea, the sunrise, and a bit of sunset as well. Yet be sure to bring a jumper, as it can get quite windy in the evening after the sunset.
Fully recommended, if you want to have a relaxing and quiet holiday on a magical island :)
