Cristina’s apartment is in an amazing central location in Florence and has a warm and cozy feel - in a very old building. It is up several flights of stairs (which is normal in Florence) and has windows onto internal light wells - which greatly reduced the street noise at night. It was very clean and well appointed.
Unfortunately there are no fly screens so we were almost eaten alive by mosquitoes on the first night. Cristina quickly resolved this by sending us some electric mosquito fume dispensers and some spray, which was greatly appreciated. If you are staying I would advise that you put these on (and spray) before going out to dinner so that you can return for a mosquito free sleep.
My only other comment is that my bed sagged in the middle and was most uncomfortable!
