My stay at Natalia and Alex's churchside apartment went beyond expectation. It is located in a rather quirky setting beside a church in the cool, hipster area of Florence with artisan shops, bars and restaurants and none of the rip-off tourist traps you may be exposed to, in the city centre over the river. However it is still very close to the city's sites, and they are easily walkable to. The flat itself was really funky and cosy, and was lovely to return to after a full day's sight-seeing.
Natalia was very nice and polite and explained everything clearly about the flat when we arrived. I have no hesitation recommending this AirBnB.
One thing to note: do not lock the front door of the apartment building to the street! We did and we unfortunately locked ourselves in when we left the keys in the flat when we were due to leave Florence! Natalia came in one hour to let us out, but it was our mistake and really unnecessary as the builing is safe and secure without locking this building front door, as it is. So many thanks again for that Natalia :-)
