My girlfriend and I stayed with Heather in late August. Her place is exactly what you expect from her post and we felt very at home. Heather wasn't there when we arrived, but getting the key to enter was a breeze.
The room and apartment are in a quiet building. You can hear the train go by, but it isn't too loud. Just think of it as being really close!
There is a lot within walking distance as well. We felt like we had too many options so we opted for roaming around and choosing a place to eat. Also, ask Heather for recommendations!
Her dog is the sweetest, we'll definitely miss him.
I would definitely recommend others stay here.
