Many thanks, Iakovs!
Your communication and willingness to help made for a great stay in Athens.
The apartment is great, especially for the number of (very nice!) bathrooms and the interesting furniture and decor.
The location is great for visiting the sites in Athens. It is true that the neighborhood is somewhat rough (locals were surprised we were staying there, considering it a bad side of town), but we actually had no problems. I suppose that part of the issue has to do with previous experiences travelling. I would follow the advice of not meandering in the small streets and avoiding being around late night.
We liked the place very much!
