The place is wonderful, centrally located (walking distance to Thissio and Monastraki, as well as Acropolis & ancient Agora) with many amenities needed, including heating, a/c, coffee machine, iron etc. The Acropolis view from the huge terrace is breathtaking. The bed is extra comfortable and all areas were spotless. I would highly recommend this place to couples and single travelers.
Two improvements can be made:
1- One of the bedroom curtains does not cover the window properly, if you are sensitive to light you will be bothered.
2- Shower (like many showers in Greece) lacks a glass door or curtain, which causes floor to be wet. Also bathroom can use some renovation: toilet seat is broken, showerhead cannot be fixed properly, etc.
