I stayed at the apartment for my last night in Crete.
Olga was very nice and helpful upon arrival and offered fresh fruits and cold water in the fridge :)
The apartment is quite cute and clean. There is an AC in the room.
The only two things were the location (about 20-30min walk from city Centre, but very close to the water) and the fact that there was no thick curtain in front of the window/glass door. Since I have a very light sleep, the sun woke me up quite early in the morning.
Overall I enjoyed the stay and recommend it for a night before leaving Crete if your departure airport is Heraklion.
