Those cottage flats are usually very well built, with gardens, and very spacious. One of Glasgow's great features in fact. They were built in their thousands mostly in the 1930s,40s,50s to house families moved from inner city rundown areas, and still make great family/starter homes. Big windows, wooden floors and doors etc. High ceilings. Solid. And very, very cheap.
Glasgow is built around a river. On the northern bank, in particular, the land slopes up quite steeply in places. Hence the steps.
