We had lovely 2 nights at M&B Guesthouse and would stay here again the next time we go to Florence. The place is a cute 4-bedroom apartment just off the historical centre, only 10-12 minutes' walk from the main train station (Firenze SMN). Many major tourists attractions are within walking distances and others are a local bus ride away. Matteo came to greet us and gave us some useful information and tips about Florence. He was very flexible and understanding with our few changes of arriving time and allowed us to keep our luggage at his place until our late train departure. We didn't get to meet Belinda and only saw Matteo once but the communication was efficient and adequate via texting. Our room was as described and shown on Airbnb website - tastefully decorated and comfortable. Because there are 3 other rooms with possible 3 groups of other guests, there may be things beyond our and the hosts' control. We found that the shared areas were nice and clean at the beginning of the day but some other guests would leave the bathroom floor wet or put rubbish in the wrong bins during the day.
Thank you, Matteo for a lovely stay.
