We stayed for about 8 days and had zero issues.
I'd suggest anyone coming, visit the house first to make a list of what's there and what you need to buy: coffee, tp, dish soap, vacuum bags for fish, spices, aluminum foil, etc. You will not need paper coffee filters for the next 15 years! Plenty of those.
The queen bed in the master is VERY soft which is probably my only 'complaint'. House is convenient to the entire peninsula (we drove to Seward a few times and down to Homer also).
With my Verizon Android phone I couldn't send or receive even a text at the house. My wife's Verizon iPhone could. My work AT&T Android phone could surf the net but at 3G/sometimes 4G only. For 'real' internet access you'll need to drive a ways down to Soldotna to the Fred Meyer store. They have free wifi you can access from your car. Not a complaint, just fyi for any looking to connect, send photos while they're visiting, etc. I personally loved the disconnect.
Sign the guest book!
My suggestions for improvement would be: to buy a new, matching set of pots/pans for the house (lids didn't seem to fit any but one pasta pot), an electric boot dryer would be a great addition too along with a French Press for coffee. Also, there's a GREAT binder of guides/maps/things to do in the area but it's long overdue for an update.
If you're looking to fish or process what you've caught there's a nice selection of quality rods available to use and everything you need to process. A cutting table, a smoker (you'd probably need to buy wood chips for it), three industrial size vacuum sealers, and a gigantic freezer and cooler in the garage labeled 'guest use'. If you prefer to let someone else do the processing you can drop your catch off at Kasilof seafood processing in Soldotna/Kenai and they'll portion and vacuum seal your catch and box it ready to go home on the airline for you. Cost was around $1.50lb.
Great cabin, super clean, would definitely book it again next time!
