I have booked this wisma MSI for 5 nights. I don't have complaining with the room. Even though the room is small but it was clean, and enough for me as solo traveler. For the 1st night I was enjoying slept. But the horrible night happened at 2nd night. At 4.51 am, suddenly I woke up because heard the voice like woman ' s voice in front of my balcony room. I thought she was talking with someone in her phone. And I don't know what she was taking about because the language was not familiar for me (English, Indonesia, Mandarin, etc). And then she tried to open my balcony room door. Of course I don't wanna to open it. And because I did not open my balcony door, then I heard she was entering her own room and walk in front of my room door and then tried to open my door 2 times. And then I informed receptionist through Whatsapp but did not replied. I also tried to call through my cellphone but no answer. And then I decided to go out, after took all my clothes and shoes and putted into my luggage. And 6.50 am I open the door quickly and bring all my stuffs and walked down from 3rd floor to 1st floor to meet the security. I talk to the security what happened and asked him to check. And then after checked at CCTV by receptionist, I was shocked to hear the information from him that it was a man who did it and he was not alone, he was with his friend. He tried to get my attention by making sounds like woman crying, so I open the balcony door. I am grateful that God saved me. And they had checked out hastily before me, without being noticed by receptionist and security. I have booked for 5 days for staying there but I decided to discontinued to stay. (just stay only 2 nights) because I did not have the courage to stay any longer. The receptionist offered me to move room on the 1sf floor, but I rejected. This is my first terrible experience staying at a hotel/guesthouse in Indonesia or abroad. This incident was really scary for me. Hopefully this doesn't happen to those of you who want to stay at Wisma MSI. I hope too my money for 3 days left can be refund.
