The apartment is great, spotless clean and super nice Kate left some goodies for us. It is spacious, well decorated with everything one might need including a variety of coffee and shower gel.
Don't be scared by the people down on the street. We never felt unsafe. We walked everywhere as it is walking distance from alternative lots-of-cool-restaurants Exharchia, to good food good bars Keramikos and trendy Kolonaki. Also walking distance to the center and Akropolis. Use the metro only if you don't like to walk.
Our stay was perfect, good value for money and hope it's free when we're back in Athens.
Thank you Kate and your sisters for the hospitality and making us feel very welcome in Athens
