Evi's mother an extremely helpful and understanding woman. Evi herself was just a call/message away for help. Evi's mom greeted us with coffee and biscuits, gave us some tips and let us leave our luggage on the last day for a couple of hours at her place. The place is very clean and has all the amenities that you need.
Evi's place is about a 5-7 min walk from the Metaxourgio.
The location as such, is away from the the crowded localities like Syntagma and Monastiraki. One one hand you enjoy a bit a peace (It could get a little noisy sometimes with cars honking and people shouting). On the other, this locality is quite emtpy and the streets in general aren't too well lit in Athens making this place look even more desolate. Most restaurants (which good reviews from LonelyPlanet or Tripadvisor) are not in this part of town.
My conclusion - "Great hosts, lovely place but in the wrong part of town"
