Both are acceptable. When learning Cebano these two words were dependent upon distance, situ being nearby but not here, sana being further away. I believe this is also the case with Indo, however, some explanation focus more on situ being a more defined location, sana a general direction, and other explanations focus on situ being informal and sana as formal, but I think that is simple because location is not as clear outside of spoken sentences. Use either.
