Very nice apartment in an easily accessible part of town! It's far enough from downtown that there aren't a crazy amount of people around, but close enough to walk to literally everything. The trains across the street runs until midnight, but with the blinds closed on the doors, it didn't bother us at all!
While we were checking in, they helped us arrange a transfer ride to the airport for our very early flight out of Athens. The driver was early, it was reasonably priced, and made our last day/morning stress-free.
Remembering to turn on the water heater before our showers was something to get used to, but we ended up just setting an alarm 30 minutes before when we wanted to wake up and it worked perfectly!
We would definitely recommend Toni's place just for the hospitality and the helpfulness of his team with arranging the ride to the airport, but being a 15 minute walk from all of the sights really made it.
