Niki's place was amazing. Our family of 4 thoroughly enjoyed our stay. First and foremost: in the extremely hot Athenian heat, the air conditioners worked amazingly. The roof terrace was a fantastic place to relax with an amazing view of parts of Athens. Beds were comfortable, everything was clean, and she even left us a small supply of goodies to get us started. It's up on the hill, so takes some climbing to get to, but no problem. Cab (kindly arranged by Niki) was able to get within 50 feet of the front door. Small kitchen facility, so definitely plan on eating out, but there are plenty of good options around. The location was super convenient to the Acropolis visitor entrance, Plaka right down the hill, the tiny alleys of Anafiotika right up the hill. Can't recommend this place more for the adventurous traveller!
