Carmine's place was great with excellent location, right in the center of Florence with walking distance to almost every major attraction. Carmine was very friendly and went put of his way more than several times to help me out when needed.
The room was comfortable, the common area was spacious and the bathroom was clean. The room overlooks the market and can be a bit noisy up until 11 pm but I'm used to this so it was fine for me. There's no AC, but with the fan it was fine. Carmine is usually not at the apartment, unless required, however his assistant was there and there were no problems. The directions provided are clear, it's very easy to find.
Would definitely stay again here in the future. Highly recommended.
