The apartment has a nice airy vibe and an overall calm atmosphere due to a well thought out interior design. The lighting is cozy during the dark hours and the windows block out noise efficiently (it is a pedestrian street only but still a popular one).
As mentioned in other people's comments everything is pretty much brand new - the sofa and bed are very comfortable and all the kitchen appliances of good quality.
It is a perfect place also for a longer stay and the elevator is a nice bonus.
Being an old building the walls are not that thick though so maybe sometimes one can hear the neighbours - it wasn't a problem for me though as it was just a couple of times during my sleep hours and I had earplugs with me ;)
