The apartment is very nice. Everything is newly renovated and works perfect. The apartment is very modern decorated and spacious.
The check in/out procedure is easy and smooth.
There is only five minutes walk to nearest metro station wich allow you to be in city center in less than 20 minutes. From/to the airport there is only required on change of metro line .. easy.
Pygmalion is a super host with great guidance to make your stay in Athens perfect. The communication is working great the entire time.
Only thing you should be aware of is that there can be a bit of traf noise.. but nothing there challenged me in order to sleep.
