The apartment is comfortable (and has air conditioning, which makes a huge difference in Florence's summer). Only possible issue some guests may face is internet: it's a limited, metered connection. We were 4 people accessing email/social media, no streaming or downloads, and we reached the limit in a few hours (it may have been due to windows 10 background downloads - if you have windows 10, remember to set the apartment's wifi connection as metered, to avoid this issue) - next day we communicated the issue to Filippo and after a few hours he purchased an additional data package, so the issue was solved.
The neighborhood is interesting and it's a short bus ride (or a 30min walk) to Florence's main attractions.
