My husband and I had a great stay at Marco's apartment. We found the apartment to be spacious and clean, had excellent wifi, and the provided amenities were suitable for our stay (we appreciated the two A/Cs especially given the summer heat!). Check-in was very easy and Marco is quick to answer questions or provide assistance. The apartment is very well located in the city centre, just steps away from the Florence Cathedral and within walking distance to all the big attractions. We certainly enjoyed being able to view the Cathedral from the hallways and it is quite a special experience to wake up to the bells ringing. There is also a little gelateria with the most delicious gelato a few doors next to the building entrance and a small grocery store across the street. As other reviewers have mentioned, there are many stairs and long hallways to go through before reaching the apartment so just a note for those with heavy luggage or mobility issues. We did manage to figure out the elevators, but it is not totally straightforward - the stairs are much more efficient. This was not an issue for us as we did not mind. We will definitely be staying at Marco's apartment again the next time we are in Florence.
