We arrived ten minutes late, Mariella's friend was patiently waiting for us. He was very friendly and explained everything.
The apartment is right next to Duomo. The building is old yet the apartment contains all the facilities, with fast Wifi. It is also quite large, fitting the four of us comfortably.
Being so close to Duomo comes with its expected noise issue, also there are forty steps of stairs. However these are all manageable.
Overall we are very happy, being able to stay in the center with a good price.
