Those with seperate daycare space in basement

Admittedly, yes, I find it a pain to be going up and down. I can't wait until we can use the alternate space I have coming available in our home, with a kitchen and bathroom. If your basement is finished, and has a bathroom, perhaps look into setting up a mini kitchenette. A mini fridge, hotplate, microwave, and so on. You can have a bin for transporting the dirty dishes, etc upstairs at naptime/end of the day and bringing clean ones back down. A good size free standing cupboard for dishes, bibs, anything else you may need. Pre-cook as much as you can, so you just need to reheat.
If that doesn't work, you just have to bite the bullet and have planned "upstairs" time and "downstairs" time.
