If you are a resident of a modern house, you will be pleased to plunge into the world of old Prague. First, you open the shabby entrance door with the key (in Prague, the entrance number is the house number), go through the spacious hall and again open the second cage door with the key, which closes access to the stairwell.
There is no elevator in the house. Then you climb up the granite! stairs to the fourth floor and open the door to the apartment with the second key. It is especially interesting to make this way in the evening in the dark. There is no permanent lighting inside the house and you need to look for a weak blue light of a switch with a timer on the wall, I advise you to press it on each floor.
The apartment is great and has a full size kitchen and a small compressor fridge.
