Long and thorough review.
To summarize: Pros: New flooring, not moldy/musty-smelling, gorgeous view, great location (close to shops and state parks), clean sheets and outdoor furnitures, host was very accommodating and responsive. Cons: slow internet, little to no reception for Verizon, AT&T, and T-Mobile.
My friends and I stayed for two nights and had a wonderful time at the cottage. Like everyone said about the A-shaped window, it was absolutely gorgeous in the morning, however, if you're sensitive to light best bring an eye mask as it gets very bright downstairs (slightly darker in the loft).
To get the "negative" thing out of the way: the internet was extremely slow during our stay (1.28 Mbps download, 6.27 Mbps upload). Also the reception in the area is not very good. These aren't really a big deal unless you need the internet; great if you want to unplug a little.
We came down from the Bay Area, and Google Maps guided us to take some very, very winding and narrow road that might be difficult to drive on at night. Even so, the house is surprisingly close to a general store (3 min drive) and a shopping center (~13 min drive). Neighbors are close by but it's very quiet! You can see the creek from the giant window, and it feels secluded. There's enough space to park 3-4 cars out on the driveway.
Read some reviews about the kitchen floors, I think Quentin had replaced the flooring since. Kitchen was more equipped than expected (old blender, hand mixer, microwave, oven, electric range, cast iron pan, mixing bowls, large and small pots, salt, pepper, oil, etc.). Moldy, musty smell was mentioned by some people in the earlier reviews, but we did NOT have that problem at all. There was a dehumidifier running when we entered the house. It's definitely a humid place and the water tank filled up rather fast. Some people noted spiders, and they're absolutely right. There were a lot of spiders hanging outside, but we only saw two spiders indoor during our stay; pesticide was also provided but we didn't use and didn't kill them either. Both the upstairs toilet and downstairs shower have timed heat lamps which would be really nice in the winter.
The sheets and blankets were so clean and smelled fresh, which is always appreciated. I stayed at a gorgeous beach house last month, unfortunately the sheets and rooms were so dusty I had such bad allergies. The outdoor furnitures were decently clean, and well-maintained unlike some reviews had stated.
Quentin was very responsive and patient, truly an amazing host!
Overall the experience was awesome and I would love to go back again for a longer stay!
