Location is really good close to Exarchia and Psirri. The Metro Station is on the line that goes directly to the Seaport, which is very convenient.
It’s also very quiet at night. And the balcony is nice!
The only thing which wasn’t great was the street in front of the house. Obviously that’s not Marinas fault but I feel like it’s worth mentioning that there are needles lying around and homeless people at night. We didn’t have any problems, though, and the place has 3 locks to get in anyway :)
