First off, the location was perfect. We were about halfway between Key Largo and Key West. The condo was nice and quiet. The view from the decks was amazing. The neighbors were not rowdy.
However:
The grill needed a serious cleaning. After it was lit to cook burgers the first night, the thing erupted in a ball of flames. When we looked at it, it appeared to have not been cleaned in years. We had to purchase a brush with stiff bristles to clean the wall behind this flame thrower, because it was covered with soot.
The WiFi was awful. One of my party had a CME class he needed to take in the middle of the week. The WiFi kept cutting out so badly that he finally gave up participating on his laptop and just called in to the class.
The kitchen needed a couple cutting boards to protect the laminate counters when we cooked. It also had a limited supply of glassware, but enough plates to feed the masses. the inside of the dishwasher looked and smelled bad. We just washed dishes by hand because we didn't think the DW would get them clean.
A few more towels would have helped. We were in the water a lot and had to do a load of towels nearly every night, so we had clean, dry towels to take with us the next day.
The "twin" beds were not twin beds at all. These beds measured approximately 65 inches long and maybe 20-22 inches wide. A twin mattress is usually 75 inches long and 38 inches wide. I am 62 inches tall with shoulders that are about 16 inches from shoulder to shoulder across my back, and I had to work every night to keep from falling off this "twin" mattress. The room was quite large enough for one "twin" and a full-size mattress, which I think would have served a larger group of potential guests. As it was, I was the only one who could have slept in this size bed. The rest of my party was at least 6 feet tall, and broader across the shoulders and chest.
In all the condo was a nice choice for our group, but it would have been better if there were actual twin beds in the third bedroom, and a few other tweaks. Everyone said that the mattresses on all the beds were comfortable, so that was a good thing.
