The check in instruction is not clear, smart lock remark as please read the website but can’t even find more info, we message the host at around 16:30 one day before check in and get the website at 20:18, tourists must a bit nervous with unclear info. We check in at 16:40 but the studio was not clean yet, the host told us the maid forgot to clean and offer us another studio, we applied for all refund rather than another disaster.
