We had some issues with our stays, but I honestly can't recomen David enough. He was nice, keep comunication open at all times and went beyond all expectations.
Our apartment not only was accurate, it was even better! It's looks just like in the pictures, is 4 min walks from Santa Maria del Fiore and 2 min from the train station (we timed it), it's refreshing with all the windows open and it has a great view. Also, the streets where is ubicated is quite and with several restaurants, cafe and pubs (we loved La Cantineta!). He also left us several suggestions of restaurants and tours we could take during our stay in the city.
The issue that we had was with the AC in the bedroom, it was making an awful noise that didn't let me sleep. But even at 3am David was available through WhatsApp trying to fix the issue. The next day he went with a technician to see what the problem was, but sadly the problem couldn't be fixed before our stay was over. We still appreciate that he went far and beyond to acomodate us. Yes, there were some setbacks, but he did everything in his power to set things straight.
