The accommodations and location were superb. The apartment is very spacious and we had plenty of room to spread out and not continually bump into each other, which was important to us as our "kids" are now fully grown. We were able to walk almost everywhere in the city center and saw so many wonderful things without ever getting into a car. It's a 4 minute walk to the Uffizi museum and less than 15 minutes to the Duomo. The river is also very close with easy access to Ponte Vecchio bridge.
One of our favorite things, however, was the view. With the apartment on the top floor it was wonderful to sip wine and watch the sun set from the living room.
Francesca is a wonderful host and great at checking in to make sure that we had everything we needed. She was able to come to the apartment and help us with some last minute printing we needed to take care of for our return journey. She also provided a great informational book in multiple languages that included recommended restaurants, museums, piazzas and shopping. I felt that the information was far more extensive than you would find in a hotel room.
I would highly recommend staying in the Sunny Penthouse!
