The photos are very accurate and the views of the Acropolis are spectacular. Overall, it was a great stay. I will break down what I saw as pros and cons, some of which echo other guests' experiences.
Pros - Views. What can I say, the balcony views are stunning. The location is a short walk to the metro and convenient to getting around. The neighborhood is really quiet at night, just what we wanted. Gregory was generally very communicative and responsive. It was a nice neighborhood with lots of things in walking distance.
Cons - We checked in around 2:30am. We have a person with a disability with us. Unfortunately the elevator was not functioning and we didn't know how to turn on stair lights. We walked up 4 flights of stairs with luggage after a very long 26 hours of flying with just our cell phones as lights. The elevator was intermittent. Gregory was so great about bringing shampoo, conditioner, and body wash but when we got there, we had about 1/2 roll of toilet paper in both bathrooms and just 1 extra roll for 5 people, 4 nights stay. When asked about getting more, he directed us to the store to buy our own. That was an Airbnb first. As others have said, you get a fitted sheet, a folded flat sheet, and 2 small pillows. We did find a blanket in the closet. The beds are very firm so if that doesn't work well for you, take note.
We had a great time in Athens!
