The location is one of the best you can find in Athens city centre by far. The hostesse's sister (I never got to meet the host herself) was kind and ok, I guess. Has an issue with the wifi which was resolved very fast, and the credit goes to Micheal, the host's son.
However, the bathroom needs serious renovation (flakes of paint peeling off the ceilings, walls, even from the bathtub's floor). The shower curtain is covered in slime and looks very dirty and disgusting to even touch. Needs to be replaced ASAP. The bathroom is very small, and a big guy will have difficulty moving around the bathtub. The aircon unit needs maintenance and looks rundown. The mattress is very uncomfortable to sleep on, pillows as well. In my opinion a small investment in a new mattress would make sense to the host.
Lastly, no TV in the room (which was not expected, but could be added in the future). The kitchenette was ok, and should you wish to make yourself a coffee or light bite, you most certainly can. Plenty of towels in the closets too, but again, the look overused. If you need a place to simply crash for a night or too, this place makes sense, as the location is indeed on of the best you can find in this price range.
