You can't beat this place in Florence. It's clean, updated, and perfectly located just a short walk (10-15min) from all of the sites. The balcony is really the selling point of this apartment, though. You can easily see the Duomo, Santa Maria Novella, and the Piazzale Michelangelo in the distance.
The host met with us promptly upon check-in making sure everything was working and even sat down to hand write a list of recommendations -- all superb.
Would definitely stay here again.
