My experience staying at rios was awesome. He meets you at his apartment upon arrival and shows you around. His apartment is located right near everything you will need for a quick Athens trip. Everything is about a 10 minute walk or less. The apartment is clean and he will hold you luggage if you have a later flight and want to explore the city after checkout. He will also call you a cab to reach the airport on the day of your departure. There is an amazing restaurant just below his place which is one of the only ones that serves food but it's by far the best place for food in Athens. There are also lots of bakeries, coffee shops and bars near by. The city center near the Acropolis also has cute dining and lots to do and see which is only about a 10 minute walk away.
