I'm a solo remote worker and highly recommend Ioanna's place if you are making your way through Athens! The amazing view alone is worth it.
Note that it is in the center of nightlife so it can be a bit loud around/after midnight in the summer, but if you are a younger group or here on vacation that should be no issue as it is quiet and very nice during the daytime for meetings, etc.
The place itself is right across from the metro Kerameikos metro stop and very accessible.
The interior is very modern, updated, and nicely decorated. I had everything that I needed and there was so much space... could see even 5 people staying here comfortably. It comes with an elevator and 2 balconies.
Ioanna is a great host, super accessible and helped me book a taxi straight from the airport to the airbnb.
Do not hesitate to book this place if it is available :)
