All I have to say is wow. This place is absolutely gorgeous, comfortable, and well-appointed. Unfortunately, I only stayed here for two nights, as I was prepping to return to the US. And it was such a wonderful stay that I gladly would have extended my trip to stay longer if it weren't almost Thanksgiving! Yannis & Rena were so kind, easy to communicate with, and arranged my transport from Piraeus Port, as well as to the airport. Both super-easy trips.
The apartment is about a 5 minute walk from the M1 line that takes you to the City Center in about 15 mins. And, because the area is a bit more residential (i.e. there aren't a large amount of hotels or anything nearby), the shops and restaurants are cheaper and, in my opinion, much better than those in the touristy areas.
When I return to Athens, I will 10/10 stay here again. Thank you so much, Yannis and Rena!
