I had a very pleasant experience to stay in Panagiotis’ place for more than one month.
This apartment has everything you need and all in good functions. Luxury space for a single tourist, also totally enough for the couple. Position of this place is great, very near to bus stops and metro(Omonia station). Restaurants, Cafe shop, and even pharmacy are all in 5mins walk.
Although sometimes may have vagabonds sit in front of the entrance at ground floor, but they are always friendly and I never get any trouble with them.
In general, this apartment is definitely one of the best choices you can have in Athens.
