Simone's place was perfect and as described. If stairs are an issue, you may want to look elsewhere. The real selling point here is the location. Great caffe outside your door, Pitti Palace within steps. Easy to walk to all of the areas of Florence that may interest you.
Simone was quick to respond and very flexible in dealing with train schedules. He also set up some fruit and pastries so I could have breakfast without having to leave the first morning.
