This apartment is actually even nicer than the photos. In particular, the kitchen is fitted with sleek, high-end appliances and has a big window with a charming rooftop view. It's located on an extremely busy, noisy street (more on that later) but the windows are nearly soundproof and the AC units are super-efficient and silent. The renovation is modern and high-end, but the historic charm remains, and the decor is hip and unique without being weird. Big closets, good bedding, well-stocked kitchen.
As others note, there's no elevator, and the ceilings are high, so it's pretty much a 4-story climb on ancient wood stairs. Be prepared.
About the street side: I had dreams of sitting perched on the little balcony sipping coffee, looking down toward the water view, but forget it. You won't even want to open the french doors: the street is extremely busy and occasionally traffic choked. As noted, the windows are soundproof, so you don't hear noise in the apartment. The back side is peaceful, so you can open the kitchen window and look out over the red-tile roofs, but that's it for outside space.
