I had similar experiences. Some brokers don't really put much effort with rental and showed whatever they had. One broker 'forgot' our scheduled viewing since he was out in the Hamptons showing a house.

I did find a nice apartment with good view (craigslist), but ultimately decided against it due to busy street and location. Also hated the fact I did all the searching, but I still had to go through broker and pay their fees. All the buildings managed by this particular management company used a single RE and there was no way around it.
