Although we never actually met Maria, we were in contact and Maria made sure we knew how to arrive from the port to Oia. The porter who came to collect us was extremely helpful, and carried our bags up many many flights of stairs (I don't think we could have managed without him!). The flat itself is small but very clean and well located - and the views are incredible, so the size really didn't bother us at all! The only problem was not having wifi, which meant working out the next leg of our journey was quite tricky - luckily the porter helped us out! Overall we had a wonderful time in Oia and would definitely recommend this studio!
