Excellent location 5 minutes walk to the Acropolis, 10 minutes from the parliament, the metro is a few steps away. Quiet area, close to many shops, cafes.
The elevator creaks at night, which makes it almost impossible to sleep. The breakfasts are also quite meager, but the location is amazing, you can walk both to the metro and to the acropolis, but I do not recommend it for a quiet night. The sound insulation is not very good.
