Marianna's apartment was great! Just as advertised; perfect location, very clean, quick responses for any concerns I had. Heads up though, the front door can be a bit sticky! You may have to ram it back and forth a bit to get the latch to open.
This aside, the apartment was just as perfect as other reviews imply. It's even easy to find, and in a great little neighbourhood. I highly recommend an evening trip up Mount Lycabettus one evening, it's situated perfectly for it!
