Antonis and Cassandra are wonderful people, I could give 5 stars just for them! Communication is great and they are very helpful.
The apartment is very nice and clean, fully equipped with everything you will ever need. The location is super, in the fisherman village of Panormos, near all the bars and restaurants. There are several wonderful beaches nearby, make yourself a favour and visit them all (they are also at walking distance). Panormos (village + beaches) and the nearby Pyrgos are among the best spots of Tinos. Highly recommended.
