shenzhen hotel suggestions?

Can anyone suggest a good quality hotel in Shenzhen for about HK$500
per night (double occupancy) where I can rent two rooms for two nights
this week (I'm in HK)? I can find a handful of Hotels on the internet,
but I've been told to be cautious about booking blind as some aren't
what they appear. If someone has a hotel they've stayed at and can
recommend, that would be very helpful.

Thanks
