We didnt like the place, sorry for our host but i think it's important to be honest. The street is dirty, buildings around are destroyed. On one direction you have nice coffee places and the Acropole at 20/30' by feet. Which is convenient. But on the other direction to Omonia you have people lying down in the streets (junkies ?), we didnt feel safe.
About the appartement it's on the groundfloor so you hear everything from the street (the first day the work in the street wakes us up very early) and from the building. The building door is just near the sofa and makes a lot of noise each time it opens or closes. I guess if you use only the bedroom it's ok but if you plan to sleep on the sofa it could be a problem. we advice NOT to go at 4 people. To our mind the photos look better than the appartement itself (and brighter than in reality).
the good points : air cond works well and there are toilet papers and detergent for a few days
