The location is wonderful. Many lovely cafes and bakeries nearby (Morning Bar is a must for coffee / breakfast!)
In the central city we recommend Anana, for amazing coffee and vegetarian brunch.
We walked everywhere as the city is so nice for walking, but it is also close to public transport if needed.
The apartment is cosy, and Rosana was really helpful when we checked in.
We did have a small issue with insect bites which I let Rosana know about, so I hope she will be able to address it.
Otherwise I think it is a lovely apartment to stay in while you explore Athens!
