We enjoyed our stay at Elena’s apartment which was managed by Manolis who was extremely helpful during check in. Everything is as per description on Airbnb. The apartment is located at a safe and quiet neighbourhood, right next to the St George hotel, and the path to Lycabettus hill. You do need a good pair of shoes to walk around the hilly area though! However, taxi is relatively cheap in Athens.
Small details like filtered coffee, snacks, washing capsules, and free local calls are very handy as our luggage was delayed for 5 days!
