I had a great time here in North Saanich/Deep Cove, would stay here again if given the chance. Perfect location to explore the northern part of the peninsula.
Rent or borrow a bike (or car) as the bus comes infrequently if you want to visit Sidney or Victoria (Sidney is very accessible by bicycle, Victoria might be better with an e-bike or a mildly adventurous cyclist -- plenty of bike lanes and drivers who are aware of (not hostile toward) cyclists).
Only thing not clear from the listing is that the dwelling is recessed about 150-200m from the main road. BUT this means the room is quite quiet and a welcome respite for this city dweller. In addition; when it's 30+ outside, inside feels quite cool all day (like 18 to 22?)
Ultimately, I had a great time here visiting North Saanich and Deep Cove and I would stay here again for a vacation if given the chance.
