We stayed in Socrates's and Margie's apartment for a week and there some points about this accommodation:
1. Apartment is amazingly located! It is in the center - so it takes about 3 minutes to go to the big supermarket or cafes, 5 minutes to the nearest metro station Thissio, 10 minutes to Acropolis, Plaka and Monastiraki area. Also should say that Thissio area is best central place (Plaka and Monastiraki are very noisy and crowded with tourists).
2. Apartment itself is very cozy, it has two beds and eating area. Kitchen is fully equipped - there are all you need if you like cooking by yourself. Moreover it is located on the first floor, so it's perfect for old people or people who has bulky luggage.
3. Socrates and Margie are wonderful hosts! They're in chat access 24/7, so if you have any questions they'll answer very-very fast. Also, Margie met us nearby the house and showed all apartment' possibilities and told about some urban places.
4. Apartment has all needed niceties for comfortable staying: fast wi-fi, iron, hairdryer, small umbrella etc. - so our staying was completely perfect. Thanks!
