Before booking this I did not know that Geylang was considered a disreputable area. However don't be put off, it has been cleaned up in recent years by the government, for a red light district it is actually very tame. The flat is in a nice building, decorated and furnished to an acceptable standard. If I didn't read up online, I wouldn't have thought that it's a red light district at all. Other than this initial worry I had no issues with my stay.
