Karen, whoever she is, is strict with her policies. So if you check in after 10pm, it’s a €20 charge. My boyfriend and I were flying in from Santorini, I did not know the time changed, so we arrived earlier to Milan. I communicated this to Karen, that we would arrive before 10pm. We got to the stay at 9:24pm, Karen said that her colleague, Rebecca, would meet us at 10pm, but we HAD to pay the €20, because she said that’s when the checkin was scheduled, even though we arrived before 10pm, she was not accommodating in that aspect. We waited for Rebecca for 45 min so she could walk us to the apartment. It seemed like it was her first time going to the apartment, she had no idea what key was the one that unlocked the apartment. There’s also 6 flights of stairs and no elevators. The place was very clean but not big at all, the pictures are misleading. It was an okay experience overall.
