We spend two weeks with our 2 year old child and liked it a lot. The apartment and it’s owner are very lovely, as you can read in the other recommendations. Carlos organised a children’s high chair for us, which was very nice.
The windows in the living room / kitchen are made of milk glas. For us it was no problem, as it was warm and we went out often. I’m colder season or if you’re at home a lot, it’s annoying I guess.
