A nice, private space for two or three. Like the other reviews stated, there was a low ceiling along one wall, but I wasn't troubled by it (I'm 5'8"). As with any basement suite, there were some upstairs noise, but very minimal.
Andrew and Julie do their best to make the place as welcoming as possible. I stayed with them near Halloween, and they had amazing decorations set up! They also hosted a party in their backyard late into the night, which didn't bother me at all. However, it's good to keep in mind people's typical behavior during celebratory times, as the guests were very loud while standing outside my window to wait for their Ubers.
All in all, a great stay in a generally peaceful neighbourhood.
