In one word - perfect. The apartment is spacious, clean, stylish. Location is great: Metro (M3) is outside the building and there are many restaurants and bars in the area.
When I needed Ioanna she was always there for me, available and helpful.
If you need absolute quiet at night it's not a place for you, since clubs are noisy, especially on weekends. I sleep with ear plugs, so no problem for me.
I'm gonna return to this apartment in my next visit for sure!
