This spot is in the bustling heart of the city. The location is perfect.
The apartment feels safe, comfortable, and so roomy. It is as good as the pictures represent. It is so nice to have a little outdoor patio. There were breakfast essentials like bread and coffee and fresh juice and a toaster, so it is okay if you arrive late. (Also a little local booze in the freezer for getting over your travels.) The bathroom is beautiful. The beds are firm. There is probably street noise late into the night throughout the city, so bring earplugs regardless of where you decide to stay.
The host, Corinna, is charming and friendly and ever so helpful. She showed me around by map and on the streets a bit. I'm sure that Corinna would be able to help you situate yourself and find anything you require. She also showed up when we were leaving and carried a suitcase all the way down to the metro; a truly kind person and a sweet face to meet, especially if it is your first time in Athens.
This is a great place to stay. I would recommend it to anyone and choose it again next time.
