Opinions and experiences on Tado thermostats

Hi guys I’m going to make some improvements on my house and I’d like to buy new thermostats.
I’ve got an hold house with very very tick walls… and I’m renting some of the rooms as Bed and Breakfast so looking on the web I realized that TADO fits for my need (theoretically speaking).
Is there someone out there that wants to share is experience and configuration with HA?
