WARNING: NOT on the "4th floor"... it's on the 5th or 6th, depending if you count "European" or "American" floors. Stairs leading from ground floor to next floor have an extra 1/2 flight, so the bottom floor of the apt is really on 5-1/2th floor or 6-1/2th floor of the building!
Loft bedroom (on the 7-1/2 floor!). The toilet is up there, too.
WARNING: low ceilings and beams in the loft; if you're much taller than 170cm (5' 7"), you will bump your head on various beams and ceiling areas, or you'll have to stoop a lot.
WARNING: The bathtub is in a glass room beside the open kitchen/living room area. I hope your traveling companions want to see you bathing!
Furnishings, linens, etc. have not been updated since (I'm guessing) the 70's or 80's, but everything works.
View is very nice; I wouldn't it "stunning".
