20 EUR discount for your first cleaning with Batmaid, if you order it starting from the below referral link:

batmaid.com/en/sponsor/RtMYBA

I recommend Batmaid for regular cleaning of your house or the end of tenency cleaning. I am happy with them cleaning my house: convenient communication, reliable, safe, tax deductible, you can easily cancel, change or keep the same cleaner; the same cleaning lady comes to me for 5+ years now.

(FYI my only interest here is that I will also receive 20 EUR discount for my next cleaning with them when you order from the link, which I regularly use, hence a win-win here).
