Hi, has anyone a recommendation for a good hotel to spend just one night in May before hopping Freedom Line ferry to Hydra Island the next morning? Efharisto:)!
Ermioni would be a good option as it also has a regular boat to Hydra several times a day.
I stayed in Ermioni a few nights and took a small ferry to Hydra for a day trip.
May be your best option and less hassle to get to Hydra:

I stayed at Treehouse Holiday Homes in Ermioni and is very nice and there are several other accommodations in town also.
