Obviously, I enjoyed this show a lot more than the MAL users average, which stands 6.68/10 as of writing. I suppose I have always been a pervy old man since I was born.
One main character is the caretaker lady, who obviously has to be beautiful and busty, and happens to molest all boys and girls who lives in her building, but somehow legal and in good atmosphere and in good taste.
As expected of Japanese anime, there's is only 1 boy but cute girls of all ages and sizes as far as eyes can see.
Seriously, apart from the ecchi, this show is full of joyful slice of life. Everyone is having a good time and being healthy like working hard at school (all the girls are in student council, - which requires being top notch at school to be eligible), competing at being GOOD at things like sport or cooking, so they are not idiots like Aho girl, which in turn, demands an slightly-intelligent spin to the ecchi scenarios. And the caretaker works hard to look after all these kids so they can have a good time. The main boy isn't criminally molesting females and acting like it's no big deal (a la 7 Deadly Sins - makes me sick) or miraculously plunging his face into panties every step (a la To Love Ru - that's the part I liked the least but I really enjoyed the rest of the show). All the girls just have different personalities, different preoccupations and create somewhat-realistic scenarios for why the boy is sandwiched between them.
So what's so bad about that?
The art and face style reminds me a lot of Kobayashi's Dragon Maid.
