Tatiana's place is lovely: bright, well equipped, super clean and quirkly decorated. It's placed in one of the most interesting areas of Milan, Isola. Isola is an area that massively changed in the past decade to become one of the most "up and coming". This means that there is no shortage of cool restaurants, bars and cafes, all within a short radius. It is really well connected too, with two undeground stations connecting you to Duomo and other landmarks in 15 minutes or so.
Tatiana has been really attentive, welcoming and reachable at all times. Strongly recommended, to get a feel of what the real Milan is like!
