My incall is very small, just over 300 sq. feet to be exact! It is recently renovated, new bathroom, new flooring, beautiful kitchen, and I really love the smaller size as it's easy to keep impeccably clean.
Originally I had a queen mattress but it made the small bedroom space too hard to maneuver. I put that back in storage and bought a Casper twin mattress and daybed frame to free up space. It looks great and I love it, but I wonder if it would be a dealbreaker for you if despite the incall being well appointed and clean, there was only a twin mattress to work with.
All input is appreciated. I wish I would have went with a full, but I redecorated during the first lockdown and wasn't as business minded as I should have been when choosing the mattress. Thank you for your opinions!
