Luana was great in meeting us even though we had to change it as we were driving from Chianti and there was traffic (GoogleMaps wasn't as accurate as normal for us in Italy).
I felt that it was a relatively safe area. Luana was always only a text or message away. She was great at replying. The home itself was comfy. The loft bedroom is a bit low so taller people i.e 175cm+ may find they have to bend their head. There was a proper kitchen if you wanted to cook.
The place is such a great spot. It's convenient to the river, the bridge, Florence S.M.Novella station AND it's right next to the most amazing locals restaurant: L'Osteria Di Giovanni. It's a 25 min walk to the amazing view of Florence: Piazzale Michelangelo.
I would stay here again. It's great!
