I would highly recommend staying here or any other location managed by Homer and Isabella. My girlfriend and I arrived in the city several hours before check-in, but the hosts were very accommodating in storing our luggage at their office nearby while we explored the city. They also provided us with an excellent list of restaurant recommendations, which led us to the best meal of our whole trip!
The apartment itself is in a great location; within walking distance to the touristy areas near the entrance to the acropolis, but far enough to be quiet and have plenty of affordable local spots for coffee and meals nearby. The place has 3 balconies that overlook a quiet residential street, 2 bedrooms, and a fairly modern kitchen. Again, I highly recommend!
