Niki is the perfect host. She always responded within a few minutes when I e-mailed her before the trip with question. She arranged a pickup for us from the airport since we were 5 people with 5 bags. She welcomed us with a smile and excellent homemade treats.
The house was extremely spacious, in a perfect location central to all local and tourist life and had a rustic and cozy feel to it. The terrace was the best part for it's view especially in the wee hours of the morning.
Overall, definitely recommended as "the place to stay in Athens". I would definitely stay here again when I go back to Athens.
