The location of the place is close to the main tourist attractions such as The Acropolis and the Plaka area, and quite close to the metro station, it is all very walkable. For the two days that we were there, we didn't have to spend any extra money on transport.
Our stay at Nick's was very comfortable as he was very welcoming and the place was very clean, tidy and big for two people. Having a private bathroom was another plus.
Nick is an extremely good and kind host who gave clear instructions to his place, and even allowed us to use his kitchen facilities and washing machine.
