I was a bit sceptical of the high star rating because there were so few reviews, but after spending a night here I was very satisfied. When you stay in Chungking Mansions you expect to have a small room, and a shower in the toilet, but often the staff are rude and unaccommodating. The staff at iTop Guest House were very chilled and friendly. The rooms were clean and the sheets were new. I did have to run between 2 blocks within the building to get from where reception is supposed to be and where it really is, but it wasn't really that much hassle and the staff were so cool it made up for it. One of the best guest houses I have stayed in in Chungking Mansions (and I have stayed in quite a few!) Only good if you are on a budget holiday and your room is not that important to you.
