We stayed here for 3 nights and had a great time. Location wise it’s perfect - 4 minutes walk to monastiraki station (which is a direct train from Athens airport) and the main square. You can walk to all the major attractions within 15 minutes (acropolis, hadrians arch, agora, etc.) which we did! There are many good options around and a dessert bar right downstairs and it’s round the corner from A for Athens, a bar with one of the best views in Athens. The apartment was very large, clean and well stocked. Whilst it is obvious Kostas does stay here, we nevertheless felt comfortable in the space and it had everything we needed. it’s great value for money right smack in the middle of Athens!
