Being a tourist (Athens)

Hello everyone!

I am only in Athens for 2 wks to network. I am looking for a trendy district in the city such as Hipster Area , small independent boutiques and lastly a great cafe/coffee place here I can probably sit for hours without getting kick out and drink my wine or coffee that has good wifi so I can have my mobile office of the day, a view of the acropolis is a big plus. Thank you!

Cheers,
Roz
