I and my teenage daughter stayed at Vasiliki's apartment which has a very central location, but in a quiet street and on the top floor. Newly renovated in a stylish modern way. The bed was very comfortable and since there is modern AC and a quiet place, we slept so well. All facilitites you need, even WiFi, ironing board, dishwasher and drying rack. The large balcony is in shadow and is very nice to sit and have your morning coffee in.
The flat is on walking distance to Athens tourist attractions, and if you do not want to walk, there is a bus stop only 3 minutes walk away, in a street where you also easily could catch a cab. The metro station is only 10 minutes walk away. The neighborhood is relaxed and there a many nice restaurants, cafés and grocery stores.
When we arrived, Vasiliki showed us the apartment and suggested places to go. She was reachable on mobile when we wanted to ask for recommendations of shopping areas. Vasiliki is very friendly and hospitable.
I really recommend the apartment and Vasiliki is a super-host!
