What we liked staying at Anastasia’s place was her quick replies and hospitality - e.g. we could help ourselves with some fruits and things for breakfast. She also advised where we could leave the luggage during our last day in Athens.
The location was convenient - not in the very center, but we never had to use the metro to visit the sites in Athens.
There was an iron in the appartment that we used.
The beds (if you like sleeping harder like us) were comfortable.
The terrace on the roof of the building has a great view to Acropolis!
The only thing that could have been better is that sometimes it was a bit noisy (e.g. cars / motorcycles passing by) even if the streets near appartment are small and there is little trafic - but when there is, you hear it.
In any case, it’s a great value for staying in Athens!
