The property is a gem and we were lucky to find it. I have food allergies so we need a kitchen when we travel so we can cook at home and the unit is well equipped. There's a Publix (nice selection, expensive) and a Winn-Dixie (less choice, cheaper) nearby. We added a kettle and coffee grinder for ourselves and future guests, but there is a Mr. Coffee and a Keurig machine.
If you want to do watersports you can go to the neighboring properties or the state park, or consider renting a kayak and having it delivered, as I saw this happening in the area. There's a pool, tennis, basketball and bacci courts. I played a few rounds of bacci with Luke, Frank and Eric, who were all very nice.
The self check-in process worked well (our flight was delayed, so we had to test it) but the process to get sublet approval from the condo association was a bit of work, requiring references, signed documents and property damage insurance. With a 28 day minimum, though, this isn't unreasonable, and the caliber of your neighbors is quite good as a result.
The cable and internet services are excellent. If the wifi password was on one of the documents I signed, I didn't see it, but I have a travel router that was easy enough to hookup so I didn't need to bother anyone about it. We had three rainy days during our stay, so we did watch a little TV.
We cleaned the place ourselves, rather than use the service that was suggested. There was a new mop (which isn't quite so new anymore, as I'm fanatical) and I left a bottle of windex under one of the bathroom sinks. The washer/dryer are excellent quality and we replaced or used our own consumables (detergent, dryer sheets, paper products, garbage bags). We were careful to put the garbage and recycling where instructed.
We'd visit again, no doubt, and would have considered extending our stay if that option had been open to us (we needed to get home and another guest was coming in after us). Key Largo is lovely and laid back, which was exactly what we were looking for, and Dr. Williams condo is a nice place to enjoy it.
