Too good.
1. Host - Clear, communicative, helpful. Miltos was very proactive whenever we had any questions about the place or the surroundings. He helped us with 'things to do' and restaurants to try in Athens. We managed to get the most out of our short trip, thanks to his itinerary.
2. Location - can't be any better. The apartment is located in Plaka and you can feel it the second you walk out of the apartment complex. It's literally 5-10 minute walk to every major attraction, restaurant, monument that you want to see in Athens.
Long story short, Miltos and his apartment beat our expectations.
Keep it up!
