Staying with Romanos and Jason was fantastic! They were gracious enough to let me both check in early and check out late, which was really helpful given my trip itinerary. The place itself could not be better located: everything was a short walk away, and I got a thorough explanation on what to see and where to go upon checking in.
The apartment appears brand new, with all the small touches that make staying there a bliss, like being able to get complete darkness in the bedroom when the sun is up.
I highly recommend it for your next trip to Athens - I know I'd certainly stay there again.
