We stayed in Intercon for three nights that is situated in Syngrou Avenue. This area is in the outskirts of the down town center but not very far. The hotel has a shuttle service every hour to the center of the town and back which is very convenient. Even if you miss one, the tram station is just a 2 min walk from the hotel which is known as Kassamouli and Syndagma (Town center) is just four stations away.
Intercon as always is a nice hotel but i didn't found the hotel staff very friendly except the concierge who helped us getting the booking to one of the finest clubs Acrotiri in Glyfada, Athens. Over all it was a nice stay.More
