The value for this listing is unbeatable. I was extremely satisfied with my stay.
Location is prime – 2 minute walk from Subway station (one stop away from the Acropolis, where you'll be spending a lot of your time). Most, if not all of the major sights in the city are within comfortable walking distance (<15 minutes). There are a ton of authentic Greek restaurants just 50 meters outside of the entrance to the Airbnb. Seems to be a safe neighborhood as well.
Space is clean and well stocked–kitchenware is all there (though there are no spices outside of salt and pepper. Oil is provided.), and the bathroom, living room area, fridge, etc. are in pristine condition. The room, while not extremely large, is more than enough for two people to stay comfortably in for a few nights. The bed is clean and spacious.
Vaki, Mike, and Tia were extremely quick to respond to any questions I had. A few times a couple issues arose, and I sent them an email inquiring about how to fix it. The listers responded in an astonishingly short amount of time–like, 30 seconds– and resolved my issue in one case by sending someone down to help out. Overall, if you have questions or concerns, they will not disappoint in helping out.
5 star Airbnb! I recommend it highly.
