Nikolas's apartment in Kolonaki is excellent. It is a great location to enjoy the centre of Athens. Getting to and from the apartment by metro is easy, with just a 5 minute walk from Panepistimiou station. Everything about the apartment is fine: the rooms are spacious, the furniture is 'period' (as the photos show) but comfortable, the kitchen and bathroom have everything a visitor needs, and the balcony is bright and sunny in the afternoon. Although Kolonaki is a lively neighbourhood with many restaurants and bars, the apartment is reasonably quiet. Nikolas is an excellent host, meeting us on arrival, providing a range of breakfast items to cover the four mornings of our stay, and communicating almost instantly to the two email questions I sent him. I'd highly recommend this apartment.
