Very centrally located, a mere 5 minutes walk from the Duomo and 10 minutes to most other tourist spots in Florence. The suite is new, with amazing beds and water pressure, making the stay cozy and luxurious. Coupled with the warm welcome and the instant communication when we landed, it was worth every penny to stay here.
Don't be put off by the fact that other apartments in the same building are not finished yet. Our stay over the weekend meant we saw no one and had the entire building to ourselves. On Monday, the workers started after 9:00.
The only thing I would note is as the apartment is very close to a main tourist area, you are going to get the noise attached to tourists well into the night. This would be true of any place close to one of the principal sights in Florence. You can close the windows to this as every room has been equipped with air conditioner units. It didn't stop us from have great sleeps!
