I manage four apartments. Generally, I have a couple stay in my apartments. Every apartment has four sets of towels for two guests to use. Every set has three towels: a small face towel, a medium hand towel, and a large bath towel. I also provide two beach towels since we are close to the beach. So there are a total of 14 towels for two guests. For every additional guest, I will add a set of towels and a beach towel.
The amount of towels can get overwhelming. I found that one of the best ways to fold them is to roll them, and tuck the end of the towel into itself. This way, it looks nice, professional, and it won’t come undone on its own.
