Pan's place was perfect for our quick overnight stay in Athens before heading out to the Cyclades. We arrived way too early for check-in, but Pan suggested a great cafe right next to the apartment where we only had to wait a short time before the cleaning staff was able to meet us and take our bags. The apartment is a bit small, but very well-appointed, with a phenomenal view of the Acropolis and the mountains north of Athens from both the kitchen and the terrace.
The neighborhood is quiet and residential, but within a 10-15 minute walk of virtually everything you'd want to see on a short stay in Athens--Acropolis hill, Temple of Zeus, Olympic Stadium. There was a produce market right around the corner on Monday selling beautiful local fruit (grapes, cherries, figs) for absurdly low prices. Pan recommended a great restaurant called To Trikyklo, that ended up being one of the top-5 meals we had in Greece, which is no small feat.
Pan responded to all my queries nearly immediately, and was really helpful in making our 24 hour whirlwind through Athens as smooth as possible. If you're a single person or couple looking for a convenient spot in Athens with authentic local vibes, I highly recommend Pan's apartment.
