I was in town with two friends to run the Vancouver half-marathon. Tanja and Mark's place is perfectly located a 10 minute walk from QE park (where the race starts). It's also 5 minutes from the Canada line King Edward station, so very convenient to get downtown or the airport/ferries.
The place itself is fantastic. A spacious, well-decorated, comfortable, and very clean basement apartment, with all of the things you would need for a short or long stay (including brand new ensuite laundry, dishwasher, and heated tiles in the bathroom! A huge bonus for us!)
The house is in a quiet and leafy Vancouver neighbourhood, away from noise, but very walkable to Mount Pleasant and Cambie Village, two of my favourite parts of the city.
Highly recommended!
