My father and I stayed in Andrea's place before I moved into my dorm in UBC and it was perfect. Andrea is such a warm and welcoming host and there seemed to be an endless amount of facilities we could use (the kitchen, tv, washing machine). When we ran into an issue with the bank where something needed to be printed, we even got to use her printer as well.
One thing we really liked was the ability to have breakfast in the mornings which was very convenient. We thoroughly enjoyed all the homemade pastries :)
In terms of the room, it was very clean and even had a mini-fridge! Safety was definitely not an issue and it truly felt like a home away from home. The location is also really convenient because her home is located less than a minute away from the nearest bus stop. If you do get the opportunity, I would also highly recommending walking a few blocks down and exploring the neighborhood as well.
All in all, it was a really pleasant stay in a quaint neighborhood with a really nice host.
