My main problem with it was how small the shower is. I didn’t think I would mind it that much but I did. The place really is tiny. I found myself wishing I had stayed in a hostel because I personally would not value my privacy more than being able to take a nice shower and I think it would have cost less.
Aside from that, Federico is a great host. The place is clean and nicely decorated. The 6 flights of stairs were a great preparation for the Eiffel Tower.
