Pros: This is a quaint basement apartment in a good neighborhood. Basic amenities are provided in a no-frills setup. Karl is very responsive and communicative.
Cons: The upstairs tenants can be heard somewhat clearly walking around, especially up and down their stairs, but they are only active during the day and the sound did not impede sleep time. Additionally, the bathroom is very small. I am 6' tall and had to half-hug the sink when sitting on the toilet, so keep this in mind if you are larger than I.
Overall I would rent this again as needed, and appreciated the responsiveness of the host.
