We had a wonderful stay at Fotini's! The place is spacious and has a sweet, personal touch. She was super nice and helpful, and left us some treats in the fridge which was a nice surprise :)
The street is not super attractive but it feels safe and it's very close to bars and cafes and to the metro station (just across the street), and it's a nice walk (about 25 minutes) to the Acropolis, so in total it's very well located.
I would definitely recommend!
