Fantastic location! Right in the middle of Oia we spent every night sitting out on the patio overlooking the beautiful church and listening to the people moving along the walkway below and music from nearby rooftop restaurants. Everything you need is very close at hand from restaurants and cafes to a pharmacy and even free (but very crowded) parking. Access is from a main walking path that is always bustling with people, this door is always locked and the apartment obviously has a locking door as well so the whole thing feels very secure. Nikolas was great to communicate with throughout the whole process. A few things that are not deal breakers but are worth noting are that to access the apartment from the street you have to go up a steep flight of stairs, its not much but if you have difficulty with stairs it may be a challenge (but also there are TONS of stairs in Oia so keep that in mind for planning). Another thing is that across all of Santorini (not just in Oia) the tap water is not drinkable so you should pick up bottled water if you're able to. Nikolas is amazing and provided a large bottle to get us started and we stopped at Supermarket AB outside of Fira to get more before heading north to Oia.
Overall our stay at Flora's House was amazing, it was so lovely to have a private retreat in the middle of Oia. We were truly spoiled with this stay!
