We had a really nice stay at Pan’s place. The apartment was cozy and clean, it had everything you could need. It is really close to most of the popular attractions, but the area was quiet and felt safe.
There is central heating in the apartment, which worked well but you also have AC in each room. Also, the washing machine was a life saver for our 6 day trip.
You have great restaurants nearby and two metro stations, if you consider to visit Lake Vouliagmeni this comes in hand.
We would certainly come back again next time we visit Athens.
