As a family of four, we were really pleased with the overall experience of both the apartment and our dealings with Claudio and his agent. Booking arrangements and communications were good all the way through including when I left something in the apartment after check-out.
The apartment was as described and as in the pictures. The internet speed was a super 240 mbit upload and 110 download. The location suited us, five minutes walk from Milan Centrale Railway station (and the Metro). It's also where the buses run to from the airports. To walk into the centre of Milan (Duomo) takes about 40 minutes or 4 stops on the Metro.
There's a good Carrefour Express supermarket about 5 minutes walk away in Via Luigi Settembrini and Caffe Napoli 2 minutes away for a cheap but excellent cappuccino (1.5 eur).
Fully recommended.
