Antonia was very friendly and hospitable. We missed our train and thus showed up 30 mins late, but she was there waiting for us and didn't say a word about it. She showed us around the place and made us feel at home.
The apartment was beautifully decorated, clean, and well stocked, and the bed we used was quite comfortable. The location was on the boundary between a run-down area and swanky shops and restaurants, but the lobby and the apartment building were both well secured and we felt safe. There is a small elevator in the building which was convenient for taking our luggage up to our floor.
