I stayed here for a month, felt totally at home and actually didn't want to leave at the end! Serafim was a great host - super-helpful and quick to respond. He showed me around when I checked in and made sure I was happy with everything. The apartment had everything you could need for a comfortable stay, even down to olive oil and herbs for cooking. Great having a balcony off each room - one got the sun for much of the day, which was a nice 'winter' bonus!
Pagkrati is a nice area - doesn't feel at all touristy and has loads of great cafes, bars and restaurants. Lots of supermarkets are within a couple of mins' walk of the apartment and it's also possible to walk to the Panathenaic Stadium in 15mins (great sunset views of the stadium and Acropolis), Plaka/Monasteraki in approx 35mins, through the National Gardens (sometimes public transport wasn't much quicker). Would definitely stay here again.
