Dear Jenny, I am so sorry to hear about that little incident...specially being so early in the morning!
During the check-in tour I accompanied your husband to the main lobby to show him the 2 opening systems of the iron black door, both the key and the automatic button you must press to open the gate. I assumed you would use the last one when leaving the premises with bags. To avoid confusion in the future I will leave written instructions at the apartment, so we can make sure none has to jump over the gate again! Glad you had a wonderful time. All the best, Carolina.
