My friend and I stayed 3 weeks in Athens at Evangelos's place. It was an ideal place for us to unwind after a long day of work. Everything was great. It was clean and he was very responsive. His family is very nice and were ready to help out when needed.
If you need to use public transport nea kipseli stop is a few minutes walk and there are a few places to eat there as well. There was a small grocery store nearby next to the church.
In short we loved everything.
