Very nice central apartment with the best view on Parthenon. The huge balcony which we didn't have the opportunity to use because of the weather. Unfortunately, it was very cold these days in Athens and the apartment is not very well isolated. Some wind can come but it's more about the noise than the cold - the heating system is very powerful in the flat.
The flat is clean and new. I'd really recommend this place if you don't plan to spend too much time inside (it's rather small but you can see this from the photos). The advantage is the balcony and location. The kitchen is very small but enough for the breakfast. Downstairs is an amazing cafe :)
Another point to take into consideration - the bed has two mattresses if it's important for you.
