The house is very clean and it seems to have been renovated. It has hot water, internet and air conditioning. it also has a washing machine, a clothes iron and a drying rack.
Near the house there is a Super Market, a kiosk, cafeterias, food stores, bank ATMs, and it is only a 2-3 minutes walk for the nearest metro stop (Agios Nikolaos - M1/Green line - Kifisia <--> Piraias)
I will consider it if I come to Athens again.
