Spectacular location, easy check in, quiet (particularly considering being in a busy part of town), responsive and accommodating hosts (they bought and delivered a pack and play for us, which was great), and fast wifi. Apartment had a good layout with plenty of space.
We had a few challenges, including missing amenities and some spots in the apartment that hadn't been cleaned (when we told the host, he addressed these issues right away). One of the air conditioner units didn't work (our host sent a repair person over but the unit unfortunately still didn't function properly).
