If avalaible do not hesitate to book this cosy, large and sunny appartment. It is located just 3 minutes walk to the train and it is renovated into a brand new and clean place respecting its past. Have stayed over for a couple of weeks so I can suggest it as a very good solution for a long term visit in the Greek capital. Alex is very friendly, responds immediately whenever we texted him. Could not have asked for a better airbnb place
