My boyfriend and I stayed at Panagiotis' for a week: we had a nice time and the apartment responds to the description. The self check-in and the self check-out are extremely easy and give you the chance to arrive and leave whenever you want. The apartment is clean and it has all the essentials. The only problem for us was the Wi-Fi: at least during our whole stay we couldn't count on it if not, sometimes, staying very close to the windows. The location is a good way to discover the old city (Ano Poli) but also to reach by walking the city center: everything is reachable within 20 to 30 minutes. I wouldn't count on busses: they're not very reliable when it comes to the old citie while they work well enough in the city center.
In the neighborhood we fell in love with Igglis, a highly advised greek taverna, with Big Little House, which makes the best breakfasts and brunches, and with the many many cats that are spread throughout the city.
Overall a good experience and a good quality-price ratio!
