I was at Cristina's appartment during a business trip and the location was very convenient, just in the centre of Florence. Cristina was very nice and everything was fine, except that I was very cold one night, since the heating was off (we were in November !), but then she put on the heating and it was better. Internet was working but very very low, so don't expect to use Skype on your computer, but you can check your mails. Everything was very clean and cosy.
