The studio is very well connected, really close to Megaro Moussikis station on blue subway line, the space is more than enough for two people, really clean, nice utilities. Athanasios and his mother, which received me in the studio were very kind and thoughtful.
The only thing that was a bit of a hiccup is the bathroom, the shower ceiling is quite low and can be an issue for tall people, except than that the place is absolutely worth it.
