Celines place was lovely! I was a solo traveler and enjoyed having space and a place to do laundry. The view of the duomo is incredible! The apartment itself is well furnished, and clean. Loved the ceilings. It’s right between the two main basilicas and on a busy tiny street, but it’s absolutely quiet inside. Easy to walk within 15 minutes everywhere you’d want to go including all major museums. I would happily stay here again.
One thing to note, like most other places you’ll find in Florence, it’s up a few flights of stairs, so plan on carrying luggage.
