These are the lovely, huge windows in our Munich apartment. They let in plenty of light, but are rather different from most windows back in North America. You can open them two ways - either they open like a door, hinging inward; or they open from the top, hinging on the bottom. The other big difference is that there are no screens on the windows! We went out and bought some fabric bug screens to install, since we are used to having metal screens on our windows back in Canada.
