Hello @Branka-and-Silvia0
I think that in Croatia things has returned to normal in terms of covid. In Brazil not yet.
Well, I do not know if my experience during these hard times can be of use to you.
I reopened my calendar in Octuber 2021.
I have not been taking bookings for less then 14 nights. (I am considering to set 28 minimun nights)
I am not taking more than 2 guests by listing.
I leave a gap of 4 days between each stay because I do not want to get stressed and for safety measures.
There are guests that are nomadic workers (they work via internet) and book the listings for more than 1 or 2 months. Sometimes even more time. I have had bookings from foreigners that use internet to work. They are usually programmers, web designers, and etc. You have to have a good internet connection, at least 35mps speed.
If you avoid groups and set minumum stay (14 nights) it can be easier to manage the listings.
Maybe less profitable, but in view of the world scenario it is not too bad.
If you quit, certainly we the hosts will miss you here. You write your posts with good humour!
Whatever is your decision, I wish you both the best.
