Location is perfect, you can easily reach the public transport or you can take a walk to some local sites. The street is silent but not deserted. As 2 girls we felt safe and didn't have any security problems even at the very late hours of the night's streets were clean and safe. Also we didn't have any sleeping problems.
The only negative thing about the room was the bin, it didn't cleaned out during our stay.
I recommend this place and I will probably choose to stay at Adroniki on my next travel.
