Location, location, location. You can’t beat it for the price in Milan. A 90-second walk from the main Duomo piazza!
The apartment was safe (doorman and such) and easily accessible.
It was very clean, however a few spots in the bathroom could use a little TLC. Still: overall cleanness 5/5.
The bed was super comfy. The sofa bed in the living room was quite alright as far as comfort, but it was very loud - the movement of my own body would wake me up. Earplugs would solve it.
During our winter stay, it was very warm inside; too warm as the radiator knob was missing so we couldn’t control it. Leaving a window ajar was a simple solution.
Overall, we’d definitely stay there again. All of those “cons” listed above were so minor that they didn’t matter too much.
