Claudia was excellent at communicating with us from the start to the end of our stay. Very helpfully she let us check in a bit earlier but we ended up arriving much later due to a delayed flight. She was patient and our check in was seamless--all very much appreciated.
The apartment was clean, incredibly spacious, and had more amenities than we needed (sulfate free shampoo!!). There was considerable noise from within the building, in particular, the residents directly above. We could hear their television, conversations, and movement of furniture. Unfortunately this is the fault of the building infrastructure and the neighbors and can't really be corrected. However, the building is in a quiet, residential neighborhood not too far from the hubbub. Thus we didn't have external noises.
Claudia was helpful when we had questions. The apartment was in great functional order so we didn't have to bug her!
Lastly, the neighborhood is well situated and very near central Milan.
