The place is located in lively Pangráti neighbourhood where you will find good bars and restaurants. It's also a short walk to Euangelismos metro station from which you can reach the airport (although the service is not very reliable), and a 20-min walk to the historic centre and the main tourist attractions.
The apartment is clean and very well equipped (AC for the hot summer, good Wifi connection...). There is also a small balcony which is always enjoyable.
The self checkin and self checkout were easy, and although I did not meet anyone in person, communication with Rizari Inn was smooth and I also received tips from the owner.
