Christos is the perfect host. We were there in January 2020. In advance we could arrange for airport pickup. He is very reliable and drives safely. We enjoyed two day trips which we agreed upon a few days in advance: to Delfi, Istria and Arachova; and to Acrocorinth and Ancient Corinth. Very reasonable prices for my daughter and I, we walked around at our pace, having agreed with Christos on a meeting time and place for the return.
The apartment is very comfortable and so very well located: Café, bakery, mini-market, supermarket... all within one street corner. We walked to the Parthenon, all the museums, Plaka, Syntagma, gardens, Licabettus Hill... We ate healthy, earthy, flavourful traditional greek food in the small tabernas. Sunny 11/13 days, streets are lined with wild orange trees, restaurants, Cafés and Bakeries. We felt very safe during the day and cooked our own dinner each night. I would go back to Christos apartment without hesitation. Winter was great to visit Athens with less tourists and cool weather.
