First the good stuff:
The flat is in an amazing location as its 5 minutes from Michelangelo's David, 5 from the Duomo and 15 from the central train station. There are wonderful eateries and bars in close vicinity. You couldn't get any better.
The flat is very cosy and characterful with gorgeous wooden beams and lovely cosy rooms.
The church bells nearby tolling are a pain. I'm a light sleeper and really suffered without being able to get a great nights sleep. The 6am toll was particularly painful. On the other hand, my boyfriend slept through.
Secondly, the shower is tiny and the hot water is rather hit and miss. There was one cold shower on our four night stay at least.
Having said all that, this is a quaint and character full flat if you are able to forgo some creature comforts. Given the location, it's great value for money.
