Tia and Mike place is terrific! The check in system is awesome as you can check in anytime you want which we did during midnight. The place is clean, room is spacious and with kitchen which is fully equipped. It's not in the city Center itself but is walkable or you can take the local trolley bus from Syntagma Square. It is a very lively neighbourhood which is nearby to restaurants and supermarket. Tia even let us store our luggage as our ferry to Santorini was quite late on our check out day. Overall, will definitely recommend to others who wants to visit Athens!
