It was a disaster. At the first, the building was under construction. It wasn't convenience and safe to carry the luggage. I was embarrassed myself that I should let my friend to stay there. Since we only had 20hours to stay in Prague, we asked the host that whether we can put our luggage at this place before the check-in time. Because the check-in office and the flat is still 15-20mins away from the tourist spot. The host Alex was willing to help us at first. We appreciated that. HOWEVER, we couldn’t open the door when we arrived. There is specific way to put the key and we should turn it to “right side” so hard. It was super stiff! But the host kept asking us to turn the key to “left side”ONLY. And he assumed that we done it wrong!! Also Alex just hang up the phone while we were talking to him. Even the technician couldn't open it at once. JUST IMAGINE! We spent much money to call and stood outside in the freezing weather. Water boiler has hdisgusting things inside. BE MINDFUL!
