Gaia's place is exactly what you see on pictures and what you read from comments. It's in the middle of Santa Maria Novella square, from where you can even see part of the beautiful Duomo. The place has a very nice size, with two big rooms and a very spacious and clean bathroom. I'd recommend this place to everyone willing to stay in Firenze and/or make Firenze a base city to visit Toscana, as the train station is 5-10 minutes walking distance.
