No need to add anything to the previous comments; Lynn is a fantastic host, and the flat is even better than in the photos: clean, comfortable and central.
But the BEST PART is definitely Dinos, the taxidriver. If you have the chance to meet him, you'll discover a helpful Athenian. Not only did he show us around the city during our trip from/to the airport, he waited for us 30 min before waking us up for our 5am return-flight (we slept through the alarm..!). Thank you Dinos, we owe you a flight for Paris!!!
