Stefan and Teo were awesome hosts - very responsive. We were two young females and felt safe in the apartment. The location is around a 30 min walk to central Athens and the areas where you would most want to spend your time. It is around a 5-minute walk to Attiki Train station which takes you to the city. However I would potentially avoid walking to the station at night as a young female - we opted to take a Taxi into the city once it got dark which was only 6 euros with FreeNow.
The place is very warm - and comes with everything you will need. There is a washing machine downstairs with a dryer (found easy to use).
Overall great stay and good value for money.
