We had a lovely stay at Elena's apartment. We were greeted by Marcelo and his wife upon our arrival, plus there were some tasty snacks and a lovely Prosecco waiting for us.
The apartment itself is superb - a short walk from Duomo yet very quiet and peaceful. There's plenty of nice restaurants in the area, and two grocery shops just 2min away.
I wholeheartedly recommend Elena's apartment. It was a perfect place for our trip to Milan. We'll definitely be back!
