Giorgos and Stelios' place was as described - well equipped, extremely clean and comfortable, and located right in the centre of the city. They communicated quickly, answered all questions, and made us feel welcome.
The central location had its pros and cons. The pros being access to the life and action of Heraklion, with all city-based activities being in easy walking distance. The cons being the noise from a local night club - which really was exceedingly loud. Even with all windows closed the music was very audible and annoying. I realise there is not much the hosts can do about this and the fact that there is air conditioning meant having the windows closed wasn't a problem re: temperature, but it was a shame not to be able to keep the wondows open or sit on the balcony in peace.
