**Horrible experience!! Not safety! Windows and door were opened and unlocked while we back at night!!! ** We went out to visit the city in the morning, confirmed all door and windows were locked before we left. By the time we returned, we found out both the windows and door were left open and unlock (someone broke in while we were out). We felt extremely frightened that we did not even dare to go back into the house, afraid that someone was hiding inside. We immediately called the host, he didn't answer the phone call few times at first. Afterward he answered but just telling us he was sleeping (like we interrupted him), and we asked him to explain what happened about the opened door and windows. He told us he gave the cleaner the wrong room number for cleaning in the afternoon, and those cleaner came inside our room and found out there was mistake as many luggages were left inside. Host asked them to leave but cleaners clearly forgot to lock the door. We were so angry that he didn't told us before we found out. Let's imagine you are in another country and found out someone came inside your room out of sudden. That's truly scary. And the host didn't seem to care a bit. Very irresponsible. It was very lucky nothing get lost as anyone could have came inside and stole our property. Very very very scary experience indeed.
