Section 223 is good as long as you avoid the obstructed view seats towards the back. Had no issues with row 4 - highly recommend that row. High up enough to be able to see the full length of the field and still know who the players were. Just a couple of sections away from the 50 yard line too. There were two jumbo trons, one on each side of us in the end zones to aid us with replays, scores, etc. We were also able to quickly exit the stadium via Gate E on the northeast corner of the stadium. This place isn't a modern marvel. They've done some improvements to it over the years but overall, it's a pretty average venue run by a less than average owner. Which is unfortunate because the Redskins have an above average fan base who are very supportive, even during the many down years.
If you ever have the opportunity to purchase or sit in the "Dream Seats" that sit the closest to the field, you can't do any better than those. They're phenomenal and come with complimentary food and beverages.
