Deni's communication via email and WhatsApp was very friendly and informative. She gave me great instructions as to how to get to her place from the metro and how much to expect to pay a cab. The ground-level suite that I stayed in is basic but complete. If you were to stay a while, the kitchen is set up for cooking (although a hot plate and mini oven were in the living room, two steps down from the kitchen). I didn't see a grocery store as you're in the heart of the tourist centre, but Deni would be sure to tell you how to get there. The best thing about this flat is the location. A quick ten minute walk and you can watch the sunrise over the Acropolis. Although it's a short block away from the tourist road and many tavernas, it's tucked away in an alley and therefore quiet enough, for Athens. I never met Deni, but Klara who welcomed me was friendly and very keen to please and make sure that I was comfortable. I was traveling alone but the flat has beds to accommodate more people, although the quarters would be very cramped.
