We enjoyed hosting Bhupesh and his family. We are grateful for his feedback because it is through guest feedback that we are able to improve on the guest experience.
Immediately after his stay, we bought a brand new microwave and toaster for the home. Moreover, given the unusually hot Seattle summer, we are having air conditioning installed mid-August.
With regards to the basement, our FAQs clearly state that the basement will be locked off. It is a separate apartment and there may be guests staying there. Those guests are NOT Airbnb-ers, but people we know personally and trust in our home. The main house, that people rent on Airbnb is completely separate/private and over 4,000 sq ft. This is the first time we've received this kind of concern/complaint and I do agree that people should be aware that while they will be alone in the main house, there's a possibility somebody will be in the basement.
I'm glad you enjoyed your stay and we were happy to have you.
With regards to unlocking the door and finding the home - those were in extremely detailed PDFs that we emailed ahead of the trip. Both documents were attached to the email where we included the code. We'll try to insert the instructions directly into the email, and not as an attachment. Thanks for the feedback!
