We loved our stay at Livia's place. The apartment is exactly as described and we were very pleased with everything. We were met right on time to be let in, the address is correct so our taxi driver dropped us right at the gate. Once inside, the instructions for wifi, heat, keys, etc., all worked flawlessly. There were basic supplies on hand, including thick towels, soap, TP, and a hairdryer. The kitchen was stocked with espresso, an espresso maker, milk, and a bottle of proseco.
The setting is through a charming courtyard and it feels very private and secure. The Navigli neighborhood is just outside of the old outer ring, so it is convenient to most tourist sites by tram or bus. The number 3 tram is right around the block and will take you to the duomo in about 10m. The metro underground is a bit farther, so we mostly used trams which are frequent and reliable. It is a very pleasant 20m walk to the Duomo. Milan's main intercity rail station is on the opposite side of town, so leave plenty of time if you're arriving or departing by train.
Navigli surprised us, with its authentic "real life Milan" feel. It's not touristy at all, but still lively with infinite choices for dining, drinking, shopping and the like. The system of canals has been developed so that it seems to be an attraction for all the Milanese, especially the young, and the specially on a Saturday night, when it really comes alive.
This was the ideal home base for our trip, as our college aged daughter was living nearby. We loved every minute of our stay.
