The apartment is in a very convenient location in the middle of Ermou Street very close to the Parliament building and walking distance to Monastiraki Square, the Plaka District and many restaurant and shopping locations. If you're an avid walker, you could easily walk to the Acropolis from the apartment as well. There are many amenities in the apartment- dishwasher, instant hot water, laundry, fast wifi, coffee and a refrigerator.
We personally wouldn't stay there again, as it was relatively difficult to sleep due to the light from Ermou below, and the apartment maintained an unpleasant mild sewage smell during our stay. The bed was also missing a top sheet- only had a comforter- which was strange for a rental.
