Eleni and Mike (Eleni's son) were simply the greatest hosts - completely flexible on check in and check out times, including staying up late on our day of arrival to meet us in person and go through everything we needed to know about the apartment.
Communication was excellent and the apartment was exactly how it was described in both words and pictures. Only slight thing of note is that the shower/shower room is rather small height wise so if you are of a larger build this may be something to be aware of - but was fine for myself and my sister (5' 9" ish). Sofa bed was really comfortable too, and there is a mattress topper you can use for extra comfort. Full kitchen appliances too which meant we could dine for cheaper (as it's pretty pricey in Athens) - there is a My Market (supermarket) on the same road as the apartment too which was great!
Absolutely fantastic location for the Acropolis and all the archaeological sites too and so worth the money paid! For wider trips out of central Athens the apartment is just 5 minute walk from Akropoli metro station which was so convenient for getting to/from the airport too (one stop on the red line to Syntagma Square and then onwards all the way to the airport on the blue line - €10 per person or you can get a group ticket for cheaper).
We thank the hosts for a wonderful stay and would definitely come back when next in Athens!
