Response from Guido:
Thank you for your nice review. The slanted ceiling is very common in Rome even in apartments not located at the last floor.
In the passage between the bed and the wardrobe, the ceiling is 180 to 190 cm high. In the sleeping area you can sit very comfortably, it's more airy than in the pictures. Only one bed and the bathroom are located upstairs, the main room and the kitchen are very spacious and with a very high ceiling!
See you again!
