Konstantinos apartment is fabulous and in a fantastic location right in the heart of Athens. The apartment itself is spacious & comfortable, main bedroom as well as a secondary smaller bedroom, so it could very well suit families. It also has a petite balcony balcony that guests can enjoy from which you can see the Observatory and Acropolis.
It's in walking distance to everywhere, with many cafes and restaurants to choose from right around the corner as well as a lovely bakery a few minutes away. Another big plus is that the metro is very close which is handy for the transport link to the airport.
Lastly I also want to say that Konstantinos is a super host, great comms, pleasant to chat to and very accomodating.
