I traveled with my husband and our 2 teen kids. Everybody just loved the place! It's not only my words. We booked for 3 nights initially - and the we extended our stay for 1 more night. After we went to explore Tuscany we returned again - it was as good as home for us! I would highly recommend to my friends and fellow travelers.
Location - 5 min from Duomo and 5 min to Uffizzi! On busy Corso street with excellent restaurants at your door. La Rinascenete luxe department store and via Calzaiuolii - on the corner.
The apartment is very new and clean - and that's very rare thing (believe me I stayed in Florence and Rome many times). The elevator - also new - something even more rare! in this 14-15th century city. The apartment is quite spacious. 2 bedrooms with bathrooms are separated by kitchen and dining area. It was perfect for us - as teenagers want space for themselves. This apartment would be very good for 2 couples as well. The kitchen has all basic appliances, so I even cooked pasta for my family couple of times)
Sleep quality -something very important for me. I always check reviews for mentioning of "noise". This apartment is absolutely quiet by night - as both bedrooms face inner yard of the building. Duomo bells woke me up at 7 or 8 - but it's about good time to wake up.
