This place is reallySleeper and perfect if you really are a HEAVY sleeper. The apartment is 3ft away from a bar and your window will be facing the music and loud noise of the several floor bar next door with musing up to 4am, and then at 7am or so, embrace yourself for the noise of what seems construction, but is actually a shoe factory with constant banging and hammering.
We have two little girls and while one of the bedrooms is fairly less noisy, half the family ended up sleeping in the living room using the earplugs that were provided by the host.

However, again if you don't mind the no sleeping part, this apartment is awesome. The location really is perfect, near great restaurants and steps away from the awesome Little Kook with great decorations and food year around. Walking distance from the Acropolis in deed. While the overall feeling was a clean apartment, the white sheets and pillows really need a deep cleaning.
The check in was straight forward, he had a little website that takes you step by step to find the apartment (note, the yellow door in of the pictures is actually red now, and if its not closed, then it's a bit confusing to find it).
