Andreas's place was really close to the city centre - there are a lot of little cafes and restaurants nearby and the nearest bus stop is just a 3 min walk away. Its about 2-3 bus stops away from the city centre (Hadrian's Arch). The house is very clean and the check in procedure was very smooth and Andreas was very helpful in providing us an early check-in as well. His father also came to pick us up from the airport and it was really lovely meeting him as well. Overall, an excellent trip to Athens, would definitely recommend!
