Before you do anything else can I suggest if this apartment is available for your holiday dates you book it straight away! The apartment is so close to all the sights , restaurants and the Plaka I can't image a better location. Not only is the location perfect but it really is super nice, it is beautifully looked after , nicely furnished and has every little thing you could need for a holiday in Athens.
The bed was super comfortable and the heating or air con guarantee a good nights sleep whatever the weather. A cute tiny internal patio gives a breath of air or smokers nook if you are so inclined. The kitchen has everything you need to rustle up a three course dinner if eating out doesn't appeal, the cosy shower room has constant hot water for a good powerful shower.
The lovely sitting / dining room is very elegant with high ceilings and classic furniture, a pleasure to relax in after a full day sightseeing. While there is a TVs with dvds we aren't much for telly watching but should you fancy a night in you would well catered for I imagine.
The area is super safe with loads of restaurants, bars and cafes steps from the apartment, while it can be city noisy in the sitting room , the bedroom is an oasis of quiet calm. (we liked hearing the city noises outside as country mice!)
I can honesty say this the best apartment we have ever stayed in, just book!
