First off, the location and price were excellent. Plenty of space as well, and the hosts were very good at speedy responses to our communications.
However, you're getting what you're paying for with this apartment. There are all sorts of small things amiss; none of which hurt the overall stay, but were all noticeable: One of the pull-out beds was basically too uncomfortable to be used. The apartment's wifi was very slow and at times unusable. The water pressure in the shower was too low. The main television remote did not work consistently. There was no toilet paper dispenser on the wall in the bathroom.
Again, the hosts were very nice and easy to communicate with, and the rate was great. It's not a luxury place, but it does the trick if you're traveling with a bunch of people on a budget.
