This apartment is close to the Panormou metro station. For me, that is a huge benefit, because the wonderful Athens metro can be used to travel to different parts of the city. The check-in process was smooth and I didn't have any issues figuring out the lockbox (I've used lockboxes before at Airbnbs). The apartment is on the top (fifth) floor, which was not an issue for me. There is an elevator for most of the floors, but I always took the stairs for exercise.
The kitchen and bathroom were small, but adequate. The kitchen had dishes and silverware, a microwave, refrigerator, kettle, and coffee maker. The bathroom had towels, shampoo, and body soap.
The heater kept the apartment warm (my visit was in January) and the bed was comfortable. The wi-fi worked well.
