The most important thing to do prior to booking is to read the listing and look at the photos. Rosemarie's review makes it clear that she did neither.
It is stated clearly in my listing description that the space is in a commercial building in a basement-like situation. That's part of the charm and what makes it unique and fun. Rosemarie and her 62 year old son had no idea that I live here either, which was weird.
On lighting: the lights were dimmed and adjusted for ambiance. My art studio has a beautiful skylight and several rows of nice, dimmable, energy efficent lights. Great lighting is very important to me especially since this is my art studio. Rosemarie asked if there could be more light. I said yes, i can adjust. She said no it's fine. I said ok.
On smoke alarms: There are smoke alarms and sprinklers. Since this is a commercial building the fire department has inspected several times in the past and required my landlord to install sprinklers. We're up to code. However, I honestly don't know if there is a carbon monoxide detector. Thanks for the tip. I'll look into it.
On ventilation: the window that Rosemarie mentions is probably double the size she claims. In addition, I have 3 fans in the space. I encourage guests to adjust them to their liking. There is a strong commercial grade vent inside the unit too. It would be nice to have another window tbh
On my space divider: My listing is classified under "shared space". This category is distinct from "private room", or "whole house". Since I started doing airbnb, in the beginning, there was no space divider at all. Guests and I were all just in the room in front of each other. Not a big deal if you're used to traveling like that. It's a cheap yet friendly style. However, some guests mentioned the lack of privacy in my reviews. I thought it would be worth trying to do something about that. So I did. I think I did it in a cool way too by hanging up this large sheet that has a dual function as a screen for my projector to watch movies. I think that's pretty cool and guests have been appreciating my creative and functional solutions. I think it's as private as a "shared space" can get. I like it. I'm going to keep it that way. I"m often at work so this "shared space" that kinda feels like a "private room" with the space divider sometimes kinda feels like you have the whole place to yourself because I'm gone so much. I think that's brilliant! Best "shared space" on Airbnb. I should win a prize.
That said, I can still appreciate that from Rosemarie's point of view my listing would not mirror her expectations. She believed she would have not just a private room but a private apartment all to herself. But no, she got the opposite. She had to share a space with an artist-guy behind a sheet in some weird basement! lol So, yeah If I were Rosemarie I would have been disappointed too. I get it. Totally!
But I must also say that Rosemarie and her son were lovely people otherwise. I could feel that they were a little uncomfortable but there was nothing I could do.
