This is a really charming and beautifully designed place. The owner is a talented architect and interior designer. Her taste is excellent in my view. She went out of her way with helpful information too, and even allowed me to keep my suitcase in the flat all day, the day I left. She was very nice indeed.
Just for women travelling alone: you may feel safer in a neighborhood with more people on the streets at night. I didn't feel safe because the street and others in the immediate vecinity (three blocks all around the apartment) were completely deserted after dark, and there was graffiti in the two perpendicular streets and in the United States this is often associated with un-safe neighborhoods. But I think that these streets may in fact be safe-- one of the rare people I passed in the street after dark was a woman walking a dog (of the poodle rather than attack variety) and she seemed completely relaxed. The graffiti may be just because there is a school across the street and perhaps the teens there like graffiti art. So it may be that I was wrong to feel unsafe. But that is how I felt.
If you feel the cold, then only go in warm weather, because the heater is an airvent near the ceiling for the living room, kitchen and bathroom combined. The bedroom, however, has a good hot air heater and one can bring one's food in there to eat, and be comfortable on a chilly, damp night.
Again, the apartment is very lovely, and even the stairwell of the building is charming with its old wooden doors and bannister, and 1900s feel. The views from the flat are of very pretty 1900s or 1800s buildings-- very nice. It's a beautiful place.
