This is a perfect place! Clean, quiet, beautifully decorated, light and with your own spacious modern bathroom. Plus, you have access to a small but well appointed kitchen and a wonderful living area that you share with other guests. I love walking so the location of the apartment worked really well for me - it was only about 10 minute walk from the bus and train station, 15-20 minutes to Florence Old Town and! a 5 minute walk to Florence Opera - but there are also plenty public transport options nearby if you prefer that.
But as always what really makes this place special is its owner. Mauro greeted me with a smile, some cantuccinis, a map of Florence and many wonderful suggestions on things to do and see in Florence. If you love art, culture and good food Mauro is your guy! Unfortunately I only stayed for 3 days so didn't manage to see even half of what I wanted. But this can only mean that one day I will be back and without hesitation will book my stay at Le tre nonne :)
