I stayed with my friend at George's and Katerina's place for 3 nights. I cannot recommend it enough! I had already read all the great comments before, but it still exceeded my expectations.
George helped us with finding out when the busses leave in the very early morning from the ferry in Fira to Oia and even let us into the apartment in the morning. During the whole stay we could always ask George in case we have any questions and he answered within minutes. We really felt taken care of and we appreciated that.
The accommodation is very central just around the corner from the bus stop and the caldera view, which allows you to get to the nicest spots in Oia early in the morning when only a few other tourists are there. The apartment also has a little terrace, which feels quite private which we appreciated a lot. Tea, coffee, toast, marmalade and even a few spices for cooking were provided. We also got a bottle of water and delicious white wine.
The mattress in the bed was quite soft (in most of the apartments we had in Greece, the mattress was too hard), so it was super comfy.
Thanks again to George and Katerina for our lovely stay in Oia! :)
