You're really lucky indeed. It wasn't always like this, but people pass away, flats are sold and you don't control who's moving in.
I'm also using Vinted to sell my things π. I love it as it's a good platform. It's present in most European countries I think.
Thank you so much for the comments and nice wishes. I wish you the same, happy new year and all the best as well my dear friend! π π
