Great location and a big and bright apartment, but I would not return.
The apartment is located on the second floor, which did not sound very high. But it was in this case around 60 substantial high steps to go up.
It is an old building and the floors are different from the new buildings. It would be more like 3rd or forth floor in any newer building. If you have bad knees like I do beware.
And there is some street noise from the street. Cars pass regularly and are very audible through the beautiful old windows. There is also a recycling place in the building, and a garbage truck passes and stops in front of the building several times a day starting early, between 7-8 am at the latest. I did not sleep well.
However, if you are good with stairs and a heavy sleeper it would be a good place.
