My wife and I went there for a business trip and pretty much just spend 4 nights at Tim's place, so we didn't have a chance to enjoy the patio and its charm. The place is very clean and organized, Tim received us late in the evening of our arrival and gave us the keys and instructions facilitating our stay. Surprised us one morning with delicious warm chocolate croissants for breakfast, what a nice touch.
It is a basement so expect some normal basement muskiness, although there is a dehumidifier running outside the bedroom, which can be a bit noisy, depending on your tolerance levels..
Other than that, I recommend it for its cleanliness, good communication and location.
