I think that in normal situation, I would have let a really good comment and note for this flat, but some points were strongly different that what we were expecting when reading the description and the comments to make our choice for reservation:
1- Even if the location is really close to the main attraction points of the center of Athens, the area has un unsafe athmosphere and we were really worried to park the car, and to come back by feet at night. It's really close to places were you can see lots of drug addicts taking their fix... so better to check where are the safe ways to walk before, not to have bad surprise when coming back.
2- The view/terrasse/rooftop was very different from what we understood when reading the description and looking at the pictures.
From the room: you're face to face with the windows of another apartment (we let the curtain closed), and no terrace. Rooftop: accessible for all people of the building (apparments + many other AirBNB), and you have to go down to reach another staircase, then go up with the lift, etc, so it's far from the room.
For the rest: clean flat, cofortable, well organised for access, not expensive, Sokol send messages if needed.
In conclusion: the flat is good, but the description and comments does not depict the reality of the area, and the pictures with the terrace view can be misleading. We based our choice mainly on these 2 points. What's more the last day, Sokol sent us a message saying he'll give us a 5 stars, and requesting not to be punished by the fact that the area is not that nice....and that he needs a 5 stars also... Maybe it explains no one mentions it???
