First, the good parts of the reservation:
The neighborhood was quiet, clean, and felt safe. The host gave us all the information we needed to self-check in early, which was good for us since we were driving from far away and did not know ahead of time the exact arrival time.
The house is very spacious even for 7 people. The living room was great and all of the furniture and decorations were neatly arranged. There was even in-unit washer/dryer.
Now onto the bad parts:
One of the upstairs shower/baths had just a linen shower curtain with a big yelllow stain at the bottom accompanied by a strong ammonia smell. The master shower had a safety hazard since there was no bathroom light to illuminate the shower. One of my group members almost tripped because of the lack of visibility.
A lot of us noticed some of our bed linens were visibly dirty. 2 of the pillow cases had hairs on the pillowcase exterior, and some blankets had visual stains. I addressed this with the host, and even though they said they confirmed with the cleaners, the host had still given us a small refund for our inconvenience.
Also, the Nest thermostat was neat, but when we tried to turn on the heater, a burnt dust smell filled the bedrooms.
Finally, we used the provided cookingware, but problem came when we tried to wash it. Inside of the dishwasher, there puddles of old, standing water that had never drained properly and moldy smell. This brought into question the cleanliness of the dishes and utensils that we had just used.
I had tried to bring it up with Airbnb support and the host with appropriate photos; however, since I reported the other issues after 72 hours of discovery, they were unable to help and the host was under no obligation to address those other issues.
Overall, my group came to a consensus that although the reservation had many good qualities such as convenience of location and group size accommodation, there were too many flaws about things we cared about such as cleanliness and lack of remediation of these issues to give a good recommendation.
