Marco's place was modern and comfortable. He was very helpful and accommodating toward our arrival, since our flights into Milan were delayed. The place was a little bit further from the city than we expected (at least 30 minutes by public transport from the apartment to Duomo), but the public transport system is very easy to understand and easy to use. Our only issue with the place concerned warmth. It was very cold in Milan during our stay (colder than usual) and we had limited hot water. We had accidentally switched off the water heater (there is a switch in the bathroom), but even after we turned it back on and let it run for a night, we did not have enough hot water for two people to take (even short) showers. The apartment was also very cold the first night, but afterwards warmed up, both from the heater and from the weather warming up a little.
Overall, a great place, in a beautiful old building, for a great price. Not much in the neighborhood, but very easy access to the city (the tram stop is right outside the front door). Grazie Marco!
