A nice place, with evening sun on the large balconies. It's just a 7€/20 minute Uber/taxi ride from the Acropolis to give you an idea. It's on a mildly busy junction, but 6 floors up you wouldn't know it.
Senait (Constantinos' cousin) welcomed us very warmly. There is off road parking and a lift which makes things so much easier.
The only critique I could give is that the shower is very small, though it does the job just fine.
