The apartment was great and Greg was really helpful with his guides and maps including tourist must sees as well as restaurant and bar recommendations/details. We arrived earlier than expected and Greg was very helpful and quickly sorted out someone to meet us. I was sick, so am grateful that the place was very clean and comfortable, with all amenities you could need (TV, kitchen, paracetamol!). Although I didn't manage to see Athens, my companions said it was all within walking distance although taxis and metros were easy to use and always close by. They loved the shopping, food and sites Athens had to offer and I definitely intend to return to the city and this apartment as soon as possible.
