The other reviews have said it - well located in the business district of Jo'burg! Near the train, Mandela square and everything else. Well maintained and very very clean, but perhaps a little small. Could barely turn in the shower! Otherwise great.
If you consider yourself to be more adventurous, then the location of this hotel, Sandton, would not be good for that. I feel that the area was not a good representation of Jo'burg. It is perhaps for the slightly more uppity class of the country. This is just my opinion! The malls etc. around the area are standard (same as all malls in every other country).
