Giovanni's apartment is an excellent choice in the Centro Storico.
Location: You cannot do better as it is on the main shopping street in the main shopping district in Milano. All of the top shops and wonderful restaurants, bars and bakeries are within walking distance. Also the Duomo, Metro and many other top sights are also within walking distance.
Comfort: The pictures do not do justice to how clean and beautiful the apartment is. The beds are extremely comfortable and the rooms and facilities are all luxury and top notch.
Service: Giovanni and Adela were extremely helpful and communicative throughout the process. They responded to requests and questions in a very timely manner before we arrived. Adela was waiting for us upon our arrival to the apartment, provided us with keys and all of the information we needed in an efficient manner and then was available to us for the balance of the trip. Excellent service throughout!
I would highly recommend this apartment if you want to truly live like a local for a few days in Milano. We certainly hope to return soon.
