Beautiful apartment, very spacious, nice design, very clean. Central in Athens, close to various nice bars (certainly go check out the rooftopbar at "Couleur Locale"), restaurants (for example "I Feel") and sight-seeing opportunities (the Akropolis, Monastiraki square etc). Upcoming neighbourhood. Close to Monastiraki metro station.
Corinna is a very hospitable host. She made us feel welcome right away, provided us with some tips and was very good in her communication.
Value for money. I would certainly recommend Corinna and this place for a city-trip or longer vacation in Athens.
