Stylianos' place will make your Athens trip worth it. A few blocks from the Metro, all the historical sites, a supermarket and great food! We stayed here because it was so close to the Metro but it ended up being the best sleep we had in Greece. The bed was great and we finally got rest.
Everything you could need for an overnight stay. The bathroom is tiny, but the shower is spacious. All the extras provided like toothpaste, cooking things, towels, etc. The couch was a bit hard, but no one is in Athens to sit on the couch all day!!
Great location, great communication, he was flexible when we checked in sooner and accommodating when we were too frazzled to figure out when our flight left. Great experience!
