I had an extended stay at this apartment and would recommend. Great little place well located in Kolonaki with its cafes, restaurants and shops. Quiet but with access to all local amenities, short walk to transport such as the Enagelismos metro station but also well enough placed to access many of the tourist sites.
Whilst the apartment balcony doesn't itself offer a view (overlooking a small courtyard) the woods on Lycabettus Hill are only a short walk away for a more natural setting.
