We have seen a lot of hotels...
We have seen a lot of hotels in Bangkok, and I must say this is easily the "best in class" in the $70 range. We have stayed in this hotel on 2 occasions, and would gladly come back here again.
The rooms in Unico Grande Sukhumvit 1 rival those in any 5 star hotel. The rooms are HUGE (really huge), and superbly maintained. The rooms we stayed in had a 29" LCD TV, a DVD player and a music system (something I havent seen in 5 star hotels). There was also a big fridge, an ironing board, microwave, electric kettle, plates, spoons, bowls and a litchen sink. This is entirely unique to Unico Grande. The beds were comfy and the linen extremely clean. There were bath robes, etc, which one usually doesnt expect in a $70 hotel.
Yes, the other reviews are correct, the hot water in the shower seems to have a mind of its own, but its really a minor issue when considering everything else thats great about this hotel.
I must say, Unico Grande is one of the best kept secrets in Bangkok.
