We stayed at the Adrainou hotel on two separate occasions. Both of our stays were fantastic. The location is great as shops, restaurants, Acropolis and other attractions are right there. On top of that, being in a mostly pedestrian district, it is calm at night. The staff is wonderful and goes out of their way to ensure a comfortable stay. They also arranged our transfers from/to the airport and islands ferry. I strongly recommend this place to anyone who wants to stay in Athens.
