I spend 4 days in Alssandro+Azadeh's house, and it was just perfect! Actually it's my second time visiting in Firenze, and I choose there for my honeymoon. Firenze was wonderful, and needless to say, Alessandro+Azadeh's house was the best choice.
Duomo was right in front of the house, and it's exactly the same you saw on the pictures. Every morning I opened the window, I could see the beautiful Duomo. Of course, check-in & check out was going well, and the comunication was also going on smoothly. I strongly recommend this house!! :)
