We were at Horizonte suites with our 3 monts old baby. The place is at a very good location just next to the sea from which it is easy and fast to reach nice places like Phalasarna beach. The flat is very clean and fully equipped with everything you need. There is a nice taverna with local food just nextdoor.
Vasilis is an excellent host, always responding very fast and having good tips.
We can only recommend this place.
