The only positive thing I have to say is the location is good. However, this is not a quiet, private cottage. This is someone's shed where they installed a bathroom. I hope that they fix said bathroom and install adequate curtains/blinds. The owners also need to inform guests in the main house that someone is staying in the shed.
All the fixtures in the bathroom leak. I didn't get any sleep the first night because the shower leaked. The bathroom is about 8" or so raised above the rest of the unit and is on a hollow box, so when water leaked it was rather loud. The toilet was dry the first night, but has a slow leak as well. The sink is not firmly attached so bumping it, it moves quite a bit and makes an odd noise when you use it.
Note that the slider was not locked on our arrival and the front door lock did not have instructions on how to secure it. If you stay here, check the slider first thing and hopefully the listing is updated to include instructions on how to lock the front door. We figured it out after some Googling and trial and error, but I can see why someone else thought it was broken.
In the afternoon on our 3rd day, a large family that is personal friends with the property owner arrived to stay in the main house and no one told them we were there. So, they immediately walked into the backyard and opened the slider while I was getting dressed. I'm not sure why they felt the need to do that, but the owner really should have told them someone was staying in the shed. Luckily, the curtains are sheer so I could see them coming and was able to duck into the bathroom and my fiancee called out "hello" and they closed the door and let us be. That's how I found out the slider was unlocked and found a weird sideways label with instructions on how to lock it.
They unpacked the makings for a large party/BBQ just outside the shed. Which I understand. They had no idea and had no rules they were beholden to, but it was also exactly what I was trying to avoid in booking a "quiet" cottage with a long list of rules for the property.
We left early, because in the evening, the hot tub and patio face the "cottage" and trying to get ready for bed was embarrassing. The sheer curtains meant we were lit up for anyone on the patio to see. I was exhausted and did not want an audience when I got ready for bed or got up in the morning. It was worth it for me to drive home and skip the last day of my vacation. I had opted for this rental rather than a hotel trying to avoid families, parties, and noise at a quiet spot near the beach. Definitely not what I expected from the pictures, descriptions, and other reviews.
Maybe we were unlucky and it usually is a quiet spot. I still would never stay here again given the poor quality of the bathroom and lack of decent curtains/blinds.
