The appartement is very clean and comfortable. The kitchen is pretty new and has everything you need if you wanna cook. The bathroom is small but very tidy as well.
Marys appartement is a wonderful homebase when in Athens. It's in a quiet, residential area with very nice little restaurants just around the corner. Perfect to end a day of sightseeing. The Akropolis and the more busy/touristy parts of Athens center are an easy 10 to 15 min walk away.
The communication with Mary was easy.
I definitely recommend staying at Marys appartement.
