The place was inexpensive and clean. It is a short cab ride or short walk to the metro, but not a very short walk to the Acropolis, etc. More like 30-45 minutes to walk to anything major.
Also, it took us about half an hour to read through and figure out all the energy saving features. You have to use a key to turn on the electricity, then flip a switch, and wait an hour for 10 minutes of hot water. Then flip the switch and wait an hour for another 10 minutes of hot water. Kind of a pain with 5 people.
Also, the AC seems to turn off after about 8 hours or so. Not terrible if you aren't planning on sleeping long, but kind of annoying after an international flight.
For anyone coming from the US, the apartment is on what we would call the second floor, FYI.
All things said and done, it is clean and it is a place to stay.
