Absolutely beautiful apartment with a stunning view! We stayed there even with two small kids, for us it was a perfect spot. If you are not sure to stay at Ano Syros, it is much calmer, cooler and more beautiful than at the port. From Ermoupolis you can take a taxi for 5€ if you don’t want to walk back up the hill.
Anna and her family were so helpful and welcoming, we lernt a lot about their life in Ano Syros. So nice to have not only an apartment but also the possibility to meet the locals and learn about their culture (and to taste their wonderful tsipuro ;-))
