Check-in via iseo argo app did not work well and the alternative would have been to pay for someone to open the door. Fortunately, we could manage to enter without the app when other people were leaving the building. Regarding the apartment itself, it was everything perfect specially its location (5 min walking distance to Piazza Maggiore), it's perfectly equal to the pictures and had all the amenities needed. Last we appreciate that Armand was always fast to answer our messages but it could have tried to answer in english.
