I would recommend staying at Ira's place to anyone. Me and my friends booked two appartments and you cannot say which one is more beautiful. It felt like home. It's comfortable, clean, quiet and Ira is an amazing host.
The neighbourhood is amazing, you need few minutes to the bus stop and few more to the metro. There is a 24/7 supermarket which helps a lot!
I'm very often in Athens and this will always be my choice for accomodation.
