Our stay in Danielle's place was okay. The place has a kitchen with everything you need. Also there are 2 TV's, a bathtub & shower, aircon etc. The place really looks nice in its Santorini style design.
Location wise its convenient because its near 2 metrostations (Victoria and omonia) which can easily bring you to the hotspots of Athens. However the place is also located in a neighborhood which is not the safest in Athens. You will see a lot of buildings with graffiti, homeless people and we even saw some junkies around the area.
The place is smaller then it looks like on the photos. For 2 people its okay, but for 4 persons the place is just not big enough.
Communication was good. We had an issue with the aircon and requested for some extra bedsheets. This was solved within a few hours even though it was already evening.
