Dimitrios is an excellent host. Top-notch! He walked us to the apartment, showed us around the place and explained a few things, and then took out a map and helped us navigate the city including recommendations for walking tours, where to eat, where to shop, etc.
The location is excellent and within walking distance of the metro (direct from the airport). You are right off the main street in downtown Athens. It is very busy all throughout the day and into the night. Most everything to visit in Athens is within a 20 minute walk or less! There is a grocery store directly next door to the apartment and many restaurants around.
Lastly, the view is amazing. The balcony space is large and has seats available. Even in our cooler weather (60 degrees F), we used the balcony because the view was so beautiful! The room and apartment was clean and we couldn't have been happier there. Dimitrios went above and beyond to make our stay great and would highly recommend staying here!
