Nik's place was as stunning as the pictures. It is a cute, quaint, and tidy flat located very close to Acropolis. It's easily accessible by train and all of the sightseeing buses. He has plenty of brochures for you to choose from. He is extremely responsive and was very accommodating. There are plenty of places to eat within walking distance. There are also plenty taxis available in the area as well. I recommend his place and will definitely stay here if I'm ever in Athens again.
