We have a great impression from stay in Daphne appartment. First of all, she managed to organize an early check in (several hours earlier, it was quite sensative for us). Also before arrival Daphne explained in details how to get to her place from the airport and where to leave the luggage before check in.
Concerning the flat itself, good option for 3-4 people. It is nice, light and comfortable with amazing balcone. Everything needed was there. The location - in quite place but near to Plaka and Acropolis as well as streets with many cafes and restaurants (something like 15 minutes of slow walk).
Highly recommended.
