Samuel and Matteo's apartment was by far the best place we have stayed at throughout our European tour. The location was excellent, apartment was cozy, and the hosts were absolutely superb.
There was plenty of space to roam around. If you choose to cook or use the kitchen, it is fully stocked. Both the hosts were always there if you needed them, I don't think I ever had to wait very long to get a response to a question. Not to mention the place is no more then a 20 minute walk from almost any landmark.
However, there was one complaint, but rather more of a caution.
The church bells constantly ringing in Florence seems almost inevitable, however that noise wasn't the issue. The problem was the construction happening in the alleyway directly below the window. I don't know who Dino is, but he doesn't apparently do his job correctly because for two mornings in a row starting at 7am he was getting yelled at nonstop. It was a little annoying for us, but we were planning on starting early anyways. However, for those who want to sleep in, you may want to confirm the construction is complete.
Don't let that steer you away though. This place is probably the best place you can get in Florence and I will for sure be coming back to Samuel and Matteo.
