Karen's place is clean, in an area where we felt safe, and near a subway station. The apartment has a nice bed, hot water and kitchen essentials if you want to eat at the apartment.
However, we did not realize that a house rule is you are not allowed to flush toilet paper in the toilet (you are asked to throw it in the garbage or pay a $350 fee if the toilet gets clogged) which we found frustrating and kind of unsanitary.
While Karen did text to check to see how we were doing, her responses back were usually hours later, even when we were asking specific/time sensitive questions about the check out process.
The Wi-Fi is spotty, which wasn't a huge deal but more than once I just stopped using it because things wouldn't load.
Overall our experience was okay, the apartment did the job (we were really just sleeping there since we were gone most of the day/evening) but we wish we would have known about the toilet issues and some of the other house rules (like if you get make-up on the towels or sheets you will be charged) that weren't listed in the house rules section of the listing when deciding if we were going to book.
