Hydra guesthouses have become very popular. They fill the gap between typical Hydra hotels and traditional Hydra pensions.
I list low to high price ranges for all accommodation. When you enquire, MAKE SURE you ask for the best price so you get the deals as the owners don't have to pay commission if you book direct with them through HydraDirect. (It's often cheaper than booking through booking.com, Airbnb, HomeAway, etc with no booking fees to pay!)
