Was in HCMC for a work assignment for 4 weeks in July 2012. Stayed here for about 3 of them, a really long time if you ask me. If you stay here expect what you pay for, it's nothing to write home about but it gets the job done. Here are some more concrete details:
THE ROOMS are clean and small. We switched rooms about 3 times, 2 of the times the showers had the rain shower-head. I think the X01 rooms have the view of the park, which is nice. The beds were hit or miss, we switched rooms once bc the bed was horrible, the other 2 were comfy.
THE LOCATION is great, a 3 min walk to the chill sky bar, 6 to Binh Thanh Market, the park is across the street (pretty safe) and the backpackers area is across the park, 3 min walk. Cabs are very easy to catch just immediately outside the hotel, using about 2 cabs per day for a month, use only the "Vinasun" cabs (green and white cabs), as they are the most honest. Short cab to the opera house rex hotel, continental etc.
THE STAFF were helpful but compared to other hotels of about the same price range, they were less attentive and friendly.
THE BOTTOM LINE (TL;DR) my work budgeted about $50USD for a hotel, after trying 3 places we settled here. I survived for 3 whole weeks straight in this place, so I am sure you will be fine for a few days.
