We(a family,2 adults,2 children) stayed at Luca's and Chiara's apartment in Milan 3 days in August 2015.It was a good experience despite the heat in Milan during our visit;40 degrees(the apartment has no air conditioning ).
When I contacted Luca,he was very helpful and took the time to tell me exactly which bus would bring me to his apartment from the airport,so we did not have to take a taxi.It took approximately 30 min.When we arrived a friend,Federico was waiting for us,he gave us the keys and showed us everything useful.The apartment is brand new and has all the necessary equipment plus basic things such as sugar,salt,toilet paper,soap,ect.I guess the apartment is around 40 square meters:bedroom,living room/kitchen, bathroom,perfect for a couple,but 2 extra persons can sleep in the living room on the sofa(it unfolds).The bedroom is very dark,but there's light in the living room in the morning,but it did not bother us since we like to start visiting in the morning.
The apartment is well located:10 minutes from the Duomo with the bus number 94,and 10 min by foot from the San Lorenzo colonnes,(a very nice area to visit)and 15 min from the Castello Sforcesco(bus 94),ect.
We recommend this apartment,thank you very much Luca,we hope to come back !
