Yeah they’re great if maintained. They do tend to have a lot of windows (and larger windows) than typical modern homes. I suspect it’s because windows are expensive and the homes still standing were generally the higher quality homes of the era. Also - no AC back then so windows were very much functional appliances.

Double hung sash windows are especially popular in this era because they are designed to maximize airflow. You’d open the bottom sash’s on the cool side of the house to let cooler air in and open the top sash’s on the other side to let hot air out. This also creates an airflow across the home.
