Carla's apartment is indeed very nice. The actual apartment is exactly as described in this listing. Few days before checking in, her daughter, Christina, emailed me a very detailed description on how to get to the apartment by bus no. 22. We had a bit of a problem to check in due to the rainstorm on our arrival date, but with Christina's direction, we were able to get to the apartment.

During my stay, I and my sister were able to chat with Carla through Google translate (as Carla does not speak English) and Carla was lovely. Even though her kitchen could not be used, when I asked Carla for a cup of hot tea due to me being sick, she made the tea for me. I'm also grateful Carla was always at her apartment every evening of my stay as my sister could enter the apartment without me (Carla gave me one set of keys and I brought the keys with me while I and my sister walked around Florence separately).

The neighbourhood surrounding Carla's apartment is quiet and safe. There's a supermarket (which name is Esselunga) within 10-minute walking distance from her apartment. Christina also recommended some eateries in the neighbourhood that were really worthy. Bus no. 22 runs frequently and stops in front of Santa Maria Novella train station. The bus also stops in several spots near Duomo.
