We are quite surprised to read your comments and I would like to reply to each of them:
1. Adriana, who works for us, upon check-in must have asked you to switch the AC off before leaving the apartment. If she mentioned electricity instead of AC she probably did not explain herself. In any case, do you usually keep the light on at your place when you are not in the apartment?
2. Two sets of apartment keys. We never provide to one couple two sets of keys and this is a quite standard procedure in other B&B/ apartments. However, if the guests request two sets of keys we have no issues in providing it. Did you ever ask?
3. We always keep extra toilet paper in the bathroom inside the cabinet under the washbasin. Maybe Adriana forgot to show you where the extra toilet paper was. However, a text message, a phone call or an Airbnb message would have sort this issue out.
4. I assume that by sky-light you mean the window balcony and you are stating that there are no curtains on the window. This is insane because the bedroom are furnished with shutter and curtains.
Thank you for your stay and hope you will enjoy your future stay in other apartments.
