We had a great time in Athens at Persefoni's place in Athens. After an initial misunderstanding in which the price went up after I had made my initial booking, Persefoni more than made up for this with going out of her way to be helpful.

The street is very quiet so you feel almost like you are not in a city yet within easy reach of the busy Acropolis area, and metro a short walk to access everything else.
We loved the vibe of the place and it is uncluttered, tidy and clean. There is a fan only in the bedroom so dont know what it would be like in the high summer but we were fine. The courtyard was an essential and welcome place to eat (the only thing I would say is that it is very overlooked by neighbouring flats so don't plan on partying out there)!

The area is great, feels like really living in Athens, not full of hotels and tourists and there is a fab pedestrianised area with welcoming and lively bars and cafes just down the road where we went often.
I would highly recommed Persefonis place and would happily return - in fact I hope to as I thought Athens was a brilliant city.
