Reminds me of a friend's studio in Paris when we were students. Except her studio was smaller and didn't have a shower (just a toilet) or a washing machine. At the time I thought her studio was quite fancy because she had a fridge AND her own toilet AND a landline. Woohoo!
By contrast, I lived in a room on the 6th floor -all stairs - that came with just a sink and no furniture (or kitchen) at all, and the toilet was a shared one down the corridor. I did, however, have a tiny balcony that had a view of the top half of the Eiffel Tower.
That studio isn't great but there's always a demand for these places, even if it's just from foreign students.
