The place is good as well as host, who kindly agreed to meet us on bus station at 3 am after our plane was delayed and it took much more time to get there. (By the way, x95 night busses from airport are really helpful.)
Pros: Friendly host, 10 minute walk from Evangelismos bus-metro station, huge appartment with 2 sleeping rooms and 2 toilets, long balcony, living rooms are like museum, lots of books, small breakfast was very handy, apotheka-grocery-cafes-toolshops nearby.
Cons: very hot at night, wifi is slow and we could connect only one device, only fan in bedroom with 2-person bed, toilets didn't close from inside by key, appartment seems a bit old, unhabited and with ghosts. :)
We are really grateful for this greek hospitality!
