A great appartment with a fantastic location.
Don't worry about the two cafés below it. Yes, there is a bit of "humming" in the court yard from (it seems) their ventilation, and a lively street in front of an appartment is what it is. But the two cafés are not in themselves a source of any major noise.
We didn't have any major noise from neighbours either.
The beds are quite soft.
The kitchen is well equipped; it has a a table for two.
A washing machine is not available, and there are no laundries nearby (but there are several dry cleaners, some of which are not insanely expensive).
Just one final tip: Depending on how sensitive you are about this, you may want to contact the owner beforehand to make sure you're ok with the bathroom situation (like getting some photos of both bathrooms, and information about the hot-water situation).
