The apartment is good value for money - it's right in the centre of everything, so it meant it was occasionally a bit noisy (we were there on Friday & Saturday) but had everything we needed. The apartment is fairly basic (e.g. you had to hold the shower head up) but it was as described and was clean, and for the location it's a great price. Theodore was very helpful and always responded quickly to my questions and it was easy to pick up the keys.
Athens is a great city, really loved all the sites and there was a huge variety of independent places to go for great food and drinks.
