Location is excellent - minutes from Monastiraki square, Acropolis is about 15 min, and shops, restaurants, grocery store all walkable.
The hotel is a bit old (bathroom missing a doorknob)..
The breakfast is healthy, filling and tasty: bread, boiled eggs, yogourt honey, jams, juice, cereal.
AC worked well though in a joined room (there were 4 if us) it meant one room was a bit cold, the other a bit warm.
Overall, you pay for what you get.
