We were very happy at Mariella's place. It was comfortable, big enough for 3, its location can hardly be better. The building is impressive and Mariella's communication was great. We found what we needed in the kitchen. The bathroom is made of 2 parts, which makes is very practical, since while one is taking a shower, another one can still wash hands or brush teeth.
We had a minor issue with the heating but it really wasn't any important to us and Mariella living next door, she was directly involved, it was easy to deal with the problem and it didn't cause any annoyance. We recommend the apartment to anyone who wants to be at a very much central location (15 min. walk to Duomo) while being only a few minutes away from the metro.
