Oltian's apartment is an ideal place for a couple to stay in Athens; very close and easy access to all of the tourist sites.
The neighbourhood where the flat is located is slightly run down, but don't let that put you off, my friend and I both felt safe walking around.
In addition, there is some noise from neighbouring apartments in the building, despite there being signs asking them to keep quiet around certain times - definitely not Oltian's fault!
Overall, the apartment is fantastic value for your money and Oltian is a great host with lots of information!
