As of lately the counteroffers I have been receiving have dropped from $225 to $188 as of now. I'm hoping it'll continue to drop to 160 or lower before I pull the trigger. The Palazzo 179 offer is still the best bet though right now.
I'm in the same boat as you my friend. I've also tried bidding up to $170 for 4-4 thru 4-6. The closest offer they gave me was $225 per night. I'll post something if I get a hit below $170.
