I had a great time staying at Paula's flat. The location is amazing! It is within walking distance (all under 30min's walk through lovely neighborhoods) to all the main sights but still in a residential neighborhood, letting you get a feel of the local life. The view of Acropolis and the city is unbeatable, what a lovely thing to wake up to. Paula was very communicative throughout, I followed through some of her restaurant recommendations and they did not disappoint!
The flat is quite small, so might be challenging if you have lots of luggage - I had a carry-on suitcase and a backpack and had no problem at all, but I can imagine it be a bit stuffy if there are more than one big suitcase.
All in all, good value, would recommend.
