Kostis and Liz are unbelievable hosts, we can't say enough good things about them. Kostis provided fantastic service, which included organizing a pickup at the port and waiting at the apartment door to take our luggage, and arranging for a great Acropolis tour with Theoni (who we highly recommend). All the little touches in the apartment (like candies on the beds & coffee/tea selection), and overall modern decorating style made for a special stay.
Four of us stayed in the unit (kids aged 19 and 12). It did not feel too cramped even though the kids slept on the sofa bed in the living room. Being able to close the doors between all the rooms, and going out onto the balcony helped ease crowding.
The unit is perfectly located. All the major attractions are within a very walkable distance, but the neighborhood is not touristy. The balcony view is amazing, and eased the pain of having to work a little bit while there (internet was very good).
We would highly recommend staying here!
