Marco's place is a suitable studio for a couple spending some time in Florence - it is very close to the Duomo, has a small supermarket nearby, and lots of restaurants and bars. Inside the studio you can find what you need for cooking, if you want to. The place is very clean and has surveillance cameras on the hallway.
I'm not sure if this was an exception, but the first night (saturday to sunday) we had some problems with some guys, who were making a lot of noise outside our window - seemed like they were coming from a nearby bar / club, and they waked us up at 4 in the morning.
We also had a bit of a problem with the door to the studio - we couldn't block it, but we based our confidence to the surveillance cameras (and the fact that we didn't leave anything but clothes inside). I'm sure Marco will fix this, as we announced him of the problem.
I think this studio is a good choice for staying in the city's center. Thank you!
