I've had a very nice stay at Eftihis' apartment. He (the owner) and George (who manages the house) are extraordinarily quick and reliable communicators. They provide extensive information about every thinkable aspect related to the stay, I've never experienced a better service with regard to this.
The tiny village of Agriles gives you access to a large variety of beautiful options if you are into hiking. That said, you should however be aware that you need a car to use this potential. As some guests have correctly pointed out, Agriles actually is accessible by public transport (bus) from Chania. However, you won't be able to start your hikes from the village itself, since there aren't any paths you could actually follow. For instance, I tried in vain to reach the neighbouring village on foot (without sticking to the main road, that is). This is mainly due to the fact that landowners fence off their properties in order to prevent trespassing, even if there's a path crossing it.
However, this shouldn't deter you from coming here if you want to hike in the beautiful White Mountains. If you're willing to drive around a bit, you'll find many terrific options. For the fit and (slightly) adventurous: Mount Gingilos, departing from the entrance to the Samaria canyon, was the most interesting hike I did. This is probably the wildest scenery you can get in the wider area, simply great. You'll need good hiking boots (low-ankle hiking shoes won't do at all) and a minimal taste for scrambling through rocky terrain.
All in all, this apartment is highly recommended. Thanks a lot to Eftihis and George!
