Nice place. Great location. The only small glitch was the limited availability of hot water. However, there was a mechanism to switch on the heater manually, which we got to know minutes before leaving. Make sure you ask about it when you check-in or compromise on shower time ;)
Constantijn is really quick in responding to any queries and he gave a real good explanation of the city which helped us a lot. I'll definitely take this house again if I visit Athens.
