The place is amazingly central. Everything is within walking distance in Athens's most commercial streets. That makes it perfect if you like to explore the city.
There's no way to access it via car only on foot -if you carry a lot of luggage that can be an issue even if the taxi can leave you in about 100m distance. No parking place available and since it is in the city's center it kinda impossible to find a parking lot for your car.
There's a bit of noise from the street down below but I guess that's normal due to the location.
The apartment itself it's a basic one, newly renovated and there's an amazing view of the Acropolis from the bed. The owner was very helpful and prompt in his replies.
