Elena's place is neat and comfortable. The room is a good size with multiple outlets in convenient locations and multiple areas for storage and laying things out. It's location is not immediately in the thick of Milan, but it's 3–5 minutes away from two different tram lines and 8 minutes away from the M5 metro. It usually takes 25–35 minutes to get from anywhere in the center back to her place. That said, it's proximity to the tram lines means that you hear the tram sounds throughout the night/early morning. It's not very loud, but it may be advisable to bring earplugs if you are extra sensitive to sound.
As for hosting, Elena's fairly hands off, but she is quick to respond when I did bring up questions about checking in, checking out, and such. Overall, this was a really handy spot to have as a home base for a stay in Milan.
