My partner and I are allergic to mold/mildew and we experienced a lot of congestion and coughing. There was no obvious culprit, but the air was musty and held an unusual scent, like cat food. It is a basement apartment, which is stated, but I didn't think of the possibility of having problems breathing. If you don't have these kinds of allergies, you're probably fine. I wish I had encountered the few reviews that had made mention of this (I later found them, when up at 4 am with a coughing fit).
I really wish our bodies hadn't reacted as poorly as they did. The pump toilet sound many reviewers mention is definitely loud but not a deal-breaker. Sage was incredibly communicative and responsive. I appreciate when hosts reach out to you proactively to get you set up for your stay. She provided very detailed instructions.
The apartment is in a great location for folks who like to just walk around and wander into stores and restaurants. It's well priced and convenient.
