Demetrius's place is beautiful and perfectly located. It is super clean, has everything you need and is very nicely decorated. It is exactly like the pictures. We enjoyed Katapola and used buses to go to Chora, to the Monastery, to Aegiale; that was very easy. We took a taxi back from Chora in the evening after having dinner there and it was €10 to get back to Katapola, very easy.
We loved our stay (3 nights) and only wished we had stayed longer :)
