Maria's apartment is a beautiful quiet space in the middle of Exarchia. It has a lovely, leafy balcony, and each of the bedrooms had air conditioning. The apartment is larger than it appears in the photos, and would be perfect for two couples holidaying together.
Exarchia itself is probably not for everyone. The square at the end of the street was full of men, who, when I walked nearby, would call or yell at me, and on one occasion, started following us. If you are a more seasoned traveller and don't mind this - then Exarchia is a very interesting place to stay, but perhaps not the best spot for young families or women travelling alone.
The saturday market is gorgeous, and there are some cute bars and restaurants nearby. Maria supplied a useful map to locate these.
The closest metro station is a ten to fifteen minute walk away, and there is a small supermarket about five minutes walk away.
