@Richard1 when I look your listing and read your comment It is obvious that you are wonderfull, caring and experience host and everything you say is reasonable 🙂 Yes, sewing kit, I've been looking to buy a small travel size one but I couldn't find it anywhere.
@Blagoje0 don't get me wrong, we do offer some freebies - parking, wifi, sat tv, AC, soap, shampoo, shower gel, cotton pads, emergency kit for ladies (tampons etc), first help kit, filter and instant coffee, tea, sugar, salt/peper/condiments, musli, oil, 2 kinds of vinegar, loundry/toilet /dish detergents, washable slippers during winter, candy on a pillow, wc paper and kitchen rolls, linens and towels... all those essentials but that's more or less our maximum.
When you say 5€ per stay is not much I can understand you because you rent on the coast where average stay is 1 week and you have just 1 apartment and your price in full season is also almost 2x higher then ours. But we are in Zagreb where the average stay is 2 nights (statistics says 1,7 ) As we can host 8 people in 2 apartments they would use per example 8 pairs of disposable slippers every 2 days and it would be 8€ x 15 checkins/month = 120€ /month Or fresh flowers 5€ x 30 = 150€/month... on top of all other bills and expences. The same math we have to use for every other freebie so I think we will stick to your chalck-board-welcome-message or Richards sewing-kit idea 🙂
