We stayed in this apartment for three months. It was a very good value with the monthly discount. We appreciated all the cleaning products, especially the vacuum cleaner. Plenty of towels and linens are provided. There are instructions for all the appliances in an envelope under the TV. The address is conveniently located around the corner from a supermarket and a metro station. I can't really think of anything negative to say about this apartment, except be careful not to drop your laundry (or anything else) on the balcony below.
Other reviews refer to the "sketchy" neighborhood on the other side from the metro, but we have stayed in a few different areas in Athens, and we didn't think there was anything particularly worse about this one. This is not the suburbs, but it is a normal working-class family type of community. The building itself is clean and secure. Ζωή is an excellent host.
