My 1 bed Morningside flat had a long narrow toilet with the smallest sink I’ve ever seen. At some point a previous owner had gone through the wall to the living room to take space to put a bath in - so there was a half-the-width-of-a-bath chunk sticking out in the living room. A friend in the New Town also had a shower in the cupboard in her bedroom, as mentioned upthread.
Also, it cracks me up that this flat is in Stockbridge yet has a Morningside sign in the kitchen. It’s only up the road! And is of course infinitely superior.....☺️
