The location is UNBEATABLE, Ольга's communication is great, and the suite is on its way to becoming a nice place to stay.
I've lived in Vancouver most of my life. The West End is by far the place you want to be. It's got ocean on two sides, and a world-class park on another. Restaurants from all over the world cluster tightly within a five-minute walk of the suite. The streets are quiet, shady, and pretty. Come here!
Ольга is a really responsive host and makes you feel very supported. If you're interacting with Dorel, the gent who helped me with check-in or in-person things, know that he's a really warm, lovely person face-to-face. His electronic communication is abrupt and brief, but it's the style of an older guy who's not much of a techie.
The suite itself was clean, with a great balcony, but quite cluttered with the current tenant's belongings and furniture. You should also be aware that almost all of the buildings in the West End are charmingly "of their time". You're getting the real Vancouverite experience, so don't expect anything too fancy or new.
All in all, I'd say this is a fantastic place to stay and will only become more so as the hosts learn from experience with AirBnb.
