We stayed in Mary and Theo's appartment for 11 days and really enjoyed our stay. The place is small and cosy and has everything you need - we especially enjoyed the possibility of drinking coffee on the balcony in the mornings, and the bed is perfectly comfortable for a siesta on a hot day. The appartment is placed in Exarcheia - around 15 mins walk from Exarchion square, and 10 mins from the poly-tech university. We really wanted to explore that specific neighborhood, but we also enjoyed not living in the centre of it. If you want to go to the beach or take a ferry to one of the beautiful Greek islands you can take a metro to Pireaus from a station 15 mins walk away from the appartment.
Mary and Theo are very helpful and welcoming hosts. They cheked in on us during our entire stay and were super flexible with both check-in and check-out. Unfortunately we didnt have much time to get to know them, but from all their messages and our short meet at check-out we can promise you that they are very nice people who will do everything to make your stay comfortable.
We will definetly recommend the place and hope ourselves to come back sometime.
