We enjoyed our stay at Pagona's. The check-in and communication were very good, the apartment is sunny and spacious and the balcony was a welcome respite and a lovely place to drink a glass of wine in the evening.
We also enjoyed staying in a less touristy part of Athens that was still close to the main attractions. And the apartment has all the amenities. Do be prepared for the decor to be slightly faded from what is presented in the Airbnb photos but I would definitely recommend this apartment, particularly if you like staying somewhere that is ever so slightly off the beaten path.
