First of all our stay at Giorgios place was very nice!
He stayed awake until 4:00am because our flight was delayed.
The next day he showed us some places on a map where we can get the best views of the city. Besides he was always available for questions (about the phone/ email). Also you can reach the Metro Station within 2 minutes from his home.
The only (small) negative point is that we got no breakfast as it was in the description (except on our last day).
After all we would stay in this modern and cozy appartment again!
