This is my second time staying at U residence 2 because it is so near to Supermal Karawaci. Both stays are relatively short and to be honest, the host is very kind, always texting the night before to inform the room number, as well as the instructions for key collection. This is my first time seeing red sheets but besides the visual scare, the room itself is kept in clean condition. Only thing to consider is the wet/ moldy smell coming from the bathrooms (I think may need to air out the bathrooms in case no guests stay for a long time, instead of keeping it closed).
