This was an impulsive booking on my behalf because of the location - unfortunately a decision that left a lot to be desired. I take responsibility for not reading reviews/the listing more carefully. We shared the place with the host and another pair of guests. The apartment smells like cigarette smoke, which made my things/me smell like smoke. It was very loud at night and we were unable to fall asleep because of the noise - music was bumping from nearby night clubs past 3am. I considered leaving and paying to go somewhere else. We would pass on this one if visiting Athens again.
On the positive side, the host was kind, helpful, and available for questions. He provided thorough directions to his apartment and offered suggestions for places to eat.
What you see is what you get - just be mindful of the smell and bring earplugs.
