Leonardo, although we did not meet, was communicative, prompt and warm. Very accommodating. His friend sent to meet us was lovely, also.
The apartment is relatively close to Milano Centrale and easy to find. Nearby metro and tram stops made getting around very easy.
Plenty of restaurants, bars and cafes within 15-20 minute stroll.
The only demerit would be a noisy main road. I am a heavy sleeper but my travel companion had some trouble.
All in all, an excellent choice.
