Great location. Teresa was a great host. Despite that her English was limited, we can sense her hospitality. She even bought is a bottle of champaign and pound cakes as gifts. This is as clean as it can be for an older place and is located near Chinatown. Food around here is definitely cheaper and there are various supermarkets nearby. We were able to walk to all the tourist attractions.
One thing we dislike is that the bathtub piping in bathroom smelled pretty bad, even when we caped it with a plug. I believe this is a temporary issue and Teresa is going to fix this.
Overall, I would recommend this place to anyone who is visiting Florence.
