Our stay at Elias' was wonderful, the place is perfectly beautiful, the room is really clean and spacious, every room has their own balcony. There is also a public area where you can relax and dive into the pool, it's one of my favorite during our stay! The house is very centric, it's practically in Fira, 5 mins by walk, very convinient to go to everywhere.
Elias was an amazing host, since this is a family run hotel, he manages everything himself, he's really helpful with everything you might need, friendly and responsible.
In short, we love Ersi Villas! 100% reccomend!
PS: Beware to rent ATV from the guys near the the villas, not really professional because we were given an unstable one that caused us an accident, afterwards we were forced to pay the damages which was not our fault.
