Stelios is both a great person and a great host. Knowing him was a real pleasure and he can also give you some great piece of advice about restaurants (with authentic Greek food) and shopping.
The flat was cosy and clean, with a nice kitchen.. The neighbourhood is absolutely quiet but you can easily reach both the center and nea chora beach on foot (~10 and 5 mins respectively).
I'd definitely recommend Stelios' apartment for everyone who wants to fully enjoy Chania!
