We stayed for ten nights at Manolis‘ place and it was perfect for our intention.
A car is recommended for the way down to Agia Galini even if the beach can be reached by foot. Sidenote: if you want to have the best food you need to go to Taverna Illios!
The AirCon worked, the fridge is big and the balcony invited to have a drink once you come home. The bed is comfy too.
We really enjoyed our stay and can highly recommend Manolis‘ place. He is really nice and responsive and even as he lives there too he is absolutely discrete.
